It stopped sending mail and moving messages between folders, junk messages stopped being moved.

I found out by a friend that they are getting the mail, but I do not get the bcc to myself and have not since 8/29/2014, so I never know it really made it.

The main problem is when I try to move files from one folder to another either by using the mouse and dragging or using the search function and then clicking "move to", it also does not move junk to the Junk folder all the time.

I find that the problem sometimes disappears when close it and the re-start Thunderbird.

I deleted global-messages-db.sqlite and as of today is working

It is back to not moving files.

Further notes (different user, same problem):

• This is a problem that started in Thunderbird 32
• This involves both automatic (filter) moves and manual moves
• This includes use of keys and hotkeys (the delete key, for example)
• Restarting Thunderbird does seem to "reset" the problem... for a while. I notice the problem most when either I've been away from the computer/program for a while or when waking a laptop computer from a sleep or hibernation state.

Deleting global-messages-db.sqlite will have no impact on folder functionality.

This is consistent with the symptoms of such a problem.
