This problem has been around a long time, and it still remains. it is very aggravating, as it never shows progress, and when it shows up (it doesn't always), it never goes away on its own.
I've had this issue across Windows XP, Windows Vista, and Windows 7.
Also, PB intermittently hangs when you CONTROL+drag a file attachment into 220.127.116.11 Pro. It OFTEN hangs when you CONTROL+drag multiple file attachments at once into 18.104.22.168 Pro. Again, that's across Windows XP, Windows Vista, and Windows 7.
These are original bugs with file attachments. Would be nice to have these eliminated. I personally suspect the reason that progress dialog is left around is the file copy operations are completed before the dialog has finished being initialized and shown, and it misses the "go away" signal.
Would be nice as a Pro licensed user to be able to drop multiple file attachments at once into PB. Right now, it is always a gamble on crashing PB and getting a corrupted file saved into PB, so I have to do it one by one. Which really then aggravates me with the progress bar hanging around on each individual attachment drag operation. Please fix this very bad behavior by version 7. As it is, PB Pro doesn't actually have a feature you advertise on the site (adding multiple file attachments), can corrupt itself on a simple drag file operation, and causes the user to have to constantly dismiss a window that should go away by itself. Since the progress bar doesn't work for file copies, a work around would be just to disable it until someone gets it working properly, as that would be an improvement to that portion of the UI.
I do love PB. I've used it since version 1. I just find the adding file attachments operation buggy, and the adding multiple file attachments completely unusable. I'd like to have the features I need and use commonly working as well as they can.
As for the rest of PB, great job! Seriously, I use it daily, and recommend it to everyone I know. I just find this one thing very aggravating every time I use it (which is every few days) so I get a dose of these bugs quite often.
Thanks for the great tool!
