Been using Thunderbird for years, seldom have problems. But starting to see the software frequently hanging in the last week or two. Most often, things will be fine, and I'll go to bed. When I wake up, the software is hanging, no messages have been downloaded for hours, the cursor is a small blue spinning circle, and the program is not responding. I have to force-quit with task manager, start it up again, then it runs fine for several hours, before doing the same thing again. Just now, I found it hung again, without having to go to bed first. I have no way of knowing if any email is being lost during this time or not, but I have no reason to think it is. The problem is not anything major (force quit, then reload is not a horrible inconvenience), but I'd like to avoid the problem. Only recent change is I created a new gmail account because one place I like to receive emails from seems to be having problems with my own domains' emails, but they don't work with the gmail account either ... go figure. The new gmail account seems to have no problems sending or receiving emails for the most part, but since this problem started happening within the last couple of weeks, and I added the new email in the last couple of weeks, could be connected.
