Suggestions? Thunderbird quitting upon attempt to get e-mail off of server

[Black]

OK, once I got the inbox empty and compacted down to 0k, it took the new mail without quitting. Moving the last year's worth back over now . . . Used to be very finicky about the inbox file being over 2 GB-- maybe it's still that same issue (ought to be under 1.1 GB once made whole again.)

I'm thinking there's a reason I stopped updating the app but can't remember . . .
