See the attached log 1. It is important to note that this does not happen on my MacBook Pro, but is consistently reproducible on my iMac indicated in the tagline. To test this morning, I downloaded .137, logged out/in, opened my main brain, then started typing the word search in the search box. Full crash.
The second log attached is what happened with the second time I tested this morning. This time I used a test brain with just a couple of thoughts. After waking the computer from sleep and opening the test brain, I typed the search term. This time the plex went blank (see attached screenshot). I've see this seen this immediately preceding the crash other occasions. Wondering if this is all related to the 5k monitor on this iMac as per this thread http://forums.thebrain.com/post/frequent-crashes-seem-to-be-associated-with-idle-time-using-sierra-3156-8300033?highlight=5k&pid=1293929919#post1293929919, or at least something graphics related, I opened my display preferences and noticed that I'd somehow switched back to the default iMac display profile. With TheBrain still open I switched the profile back to sRGB IEC61966-2.1. Voilia! The plex immediately refreshed and my thoughts were there again.
All of the recent versions of TB9 have performed well on my laptop, noneon my much beefier iMac. I hope this is still being addressed. There are a lot of these machines in the hands of those in publishing/design. If it was my only computer I'd have a much different opinion of the state of TB9.
To close this line of thinking I put the computer to sleep a third time, this time knowing the display profile was set to sRGB IEC61966-2.1. Upon waking and doing a search, I still saw the quick flash of gray, blank plex but the program did not crash. (I know the logs are cumulative, but I've included this one as a third in case that makes it easier to follow.)
Hope this helps
