My local folders do not appear anymore in the left panel.
I've been using T'bird in "classical" layout so far, quite without problems for some time. I nevertheless had to click on a folder name to make the others reappear sometimes.
Now,regardless of the layout and of the left panel (All, Unified, Favorite...) most of the folders I created disappear: there are many folders below the "PL Action !" in the screen copy, and I don't see them anymore.
So, imagine the cklicking I need to do (between the left panes) to find what I need!
Also, instead of having a top "IN" folder containing sub folders for every account, I have the opposite since a few days: top is the account sub is the "IN" (and OUT; DRAFT,etc). So I have to dig through all my accounts to list all my incoming (read or not) mail.
Apple MacBook Pro under MacOS X 10.6.4 (Snow Leopard)
Thunderbird 3.1.1 (I had an Apple kind theme installed. It worked for a while with it. I removed it but the problems remained).
Thanks for any help.
