Harlan recently announced the alpha update 234 includes a fix for the "stuck notes" issue:
> (#4325) Notes sometimes do not update when navigating to another Thought

Unfortunately, even with the 234 update, I am still having problems with notes not updating on my Win7 notebook installation. (Will check my Desktop PC installation later today.)

In the meantime, the output log from my notebook is attached.

Just now tested the stuck note issue on my Win7 desktop installation of TB9 (234), and the problem is still occurring here, too. However, the issue is compounded now by how slow TB is running.

To illustrate these issues (slow performance and stuck notes), I've created a video recording of TB loading, followed by my attempts to navigate and edit notes in TB. Please note that TB performance in this video is actually faster than it often is on this computer:

Output log and a screenshot from my task manager are again attached.

Hope this additional information is helpful.

Yeah, that’s all but unusable. Have you tried closing all other programs and background processes to rule out conflicts? Also if you are running an anti-virus software, try disabling and running TheBrain for a short period of time just to see if it makes a difference. If it’s being particularly aggressive on monitoring disk activity it could cause something like this. Basically rule out that another program is interfering. 

I think they already asked you to make sure you have enough free HD Disk space. That could also cause slowness. I’m assuming the database is stored on an internal HD and not one attached to a USB port. Those are the obvious things to check for off the top of my head.
Are you seeing slow behavior from any other programs or anything else that could indicate a problem with either the HD or memory? F.ex programs increasingly becoming unstable and crashing?

I would also say the stuck note in your video is not the same as the one that was resolved in the release notes.
It seems to me to be a case of extremely slow processing from the program, and is probably causing all kinds of issues, that are really just symptoms of this larger issue. Basically until this is resolved it would be difficult to tell what is a bug and what is related to the slowness.

If none of the above reveal anything I would email support and work wit them directly to determine the cause.

Metta,

Thank you for posting and sorry to hear/see that the fix is not improving the application for you.  I'll make sure that engineering gets your Output.log file into the queue as soon as possible.

Thank you,
Matt

Metta,

I'm also wondering about some of the things Zen has mentioned.  Anything else running slow?  I'm not sure that this is the same notes issue that was recently repaired - seems like a result of the general slowness of the app.

Thanks,
Matt

Hi Metta,

Sorry to be the bearer of bad news, but I watched the video and it is apparent that there is something very wrong with your system even before you launch TheBrain.

The performance monitor widget onscreen is completely static as far as I can tell. It shows CPU at "00%" and memory at "28%" and never changes throughout the entirety of the recording. CPU cannot possibly be at 0% given that you are recording the video, launching the app, etcetera. Also memory cannot possibly be unchanged from when you launch the app until it completely loads. On my Windows box, CPU sits at 1% when nothing is open or doing anything at all and just moving the mouse on the desktop without any programs other than Task Manager makes the CPU jump up to 5% to 7%. This shows that even the performance monitor application is not able to run properly and that is what is causing it to fail to update it's display so it erroneously shows 0% and 28% continuously.

In terms of what we see happening in TheBrain: The application is completely unusable. I do not believe the "stuck notes" issue is happening at all but rather that everything is running extremely extremely slowly. I've never seen it run so slowly ever and I am surprised it is working at all given how slowly everything runs. To look at one specific example, when the program first opens, the "hints" display shows a gray box underneath it... This is an artifact of the display calculating the height of the dialog when it is first shown. When that calculation completes, the dialog is resized and the gray area disappears. Normally this takes less than 1/5th of a second and most people don't even notice it except as a brief "flash" at startup. However, on your recording, it took about 36 seconds. In other words, the application is running about 200 times slower than normal...
Regards,
-Harlan

Thank you all for your helpful feedback and suggestions. Your observations, Harlan, make good sense, and "200 times slower than normal " pretty much sums up the issue. (The strange thing is that despite all the issues you noticed with TB and my CPU, I had absolutely no problems with any of my other software applications.)

I also appreciate your suggestions, Alex and Matt, to check my antivirus program. I had actually been wondering if that might be an issue -- and, sure enough, when I turned off my antivirus program (WebRoot) several weeks ago, TB9 and TB8 were both lightning fast, so I assumed troubleshooting WebRoot was the place to begin.

This morning I finally had a chance to follow-up on this, and I just now spent several hours working with WebRoot tech support to resolve a corruption issue in WebRoot. Hopefully the speed and performance issues with TB may now improve as a result of clearing up this issue.

In the meantime, though, I am very concerned now by another issue that cropped up when I was previously running TB9 with WebRoot turned OFF: notes from 2 different V9 test brains completely disappeared, including notes from a brain I wasn't even working in.

Unfortunately, I have no idea now how many thoughts in my version 9 test brains may have been similarly affected -- and at this point there is no way of really knowing what happened when the data disappeared since I was completely focused on trying to retrieve the lost notes, and missed my opportunity to capture my output log.

However, I'm extremely concerned now this data loss issue may be internal to TB9 since my antivirus program was not running at the time the data disappeared.

Any additional thoughts on the data loss issue? Specifically, how to prevent and troubleshoot?

I have never had notes disappear in my using v9. 
First, do a search to make sure they aren’t on a different thought or link. 
Then, I would try to determine if there was anything about the notes that is different. Either the way I captured them or the content. Otherwise I would think about the sequence of events that occurred (for example were you switching between tabs as you were typing, or was it syncing) and see if I can recreate and email support with the details.

Once I thought notes disappeared but I had written them on a link by mistake. [smile]

Oh, also did it occur after you resolved the speed issue or before? 
If before your antivirus may have been interfering with the read/write and the notes were never written/saved to the program.

Thanks for your prompt feedback, Alex.

The data loss occurred before WebRoot was fixed, but it happened while WebRoot was turned off.

There was nothing unusual about the way the data was entered. No cut/paste, just simple text entry.

In the case of data lost from the brain I was NOT working in, I know the data had been successfully saved and synced -- on multiple occasions. It was specifically a note to TB engineers saved on the home thought of a test brain which had been exported and shared with TB staff during this troubleshooting process.

In the case of the brain I WAS working in, I know the data was not saved on a link by mistake because it had been successfully synced with another brain installation on my notebook computer.

A search for the data in the brains from which the missing data has disappeared now brings up nothing at all.

Metta,

You mentioned that you had synced.  Can the note content be seen in the web client Brain or on another machine that you may have synced to?

Thank you,
Matt

Thanks for checking in, Matt. I provided more specific details in our current help ticket.

The short answer is that the content I lost in two of the V9 brains had been previously synced with another installation on my notebook computer, and I was able to retrieve the missing content there.

However, I have no idea how many other notes may have disappeared in the 5 small test brains that were open during the time this known data loss occurred.

I only noticed 2 missing notes in 2 different brains, at which point, I feverishly began moving and saving my content elsewhere.

Once my content had been archived outside of TB9, I completed the sync with my notebook brain, and now the content is lost there, too.
