The latest update makes the program run so slow it's almost unusable. If you deal with a lot of email the time between hitting the delete key and the next e-mail has gotten 10 times longer it seems.
Yup. It seems to be working today but now when I try to send, the program sometimes never will. I must cancel the send and hit send again, then it goes through? I'm not sure if it's Thunderbird or my mail server.
I have the same issue. When I click to download e-mails, it tells me it's processing and to wait. The only cure is to re-boot the program. This new version is buggy!
