The pros and cons of upgrading (cont'd).....

[poltr1]

So I downloaded and reinstalled Thunderbird 2.0.0.22 in the same location it had been. And it appears on first glimpse that all my email, settings, and filters are gone. I did a little bit of searching, and was able to find all my messages from fuse.net from the time I started the account last year up to last week, when I last downloaded my email. (Whew!) My Gmail account was set up as an IMAP account, so my email should still be there on the server; all I had on my PC was a copy of the headers.

So now I wait for the downloads once more.
