I do have a lot of e-mails (I rarely delete anything) so it looks like this could be the cause ???

One other symptom is that I cannot add any other accounts to the Unified Folder list (right-click on Inbox --> Properties --> Choose) - The folders for the accounts, that do exist (I can send E-Mail from them), are not listed

Any ideas ? Thanks, -Graham-

Sorry - here are the errors . . . . .

Thanks for the screen shots.

I see numerous 3pane and other errors, so I haven't zeroed in on a precise solution. Can you save the log and email it to me? right click in the error console to show how to save it to a file. I will send you a private message with my email.

Hello,

is there any news on this ?

(If I have to reinstall I first need to find out how to correctly save all my various e-mails)

Thanks.

I just found your console log email in my spam folder.

I don't have a solution for you, but you might be seeing https://bugzilla.mozilla.org/show_bug.cgi?id=1869685

What happens if you do Help > Troubleshoot Mode?

Hello Wayne, I think I'm getting closer to finding the source of this problem . . . . .

I de- and re-installed Thunderbird (moving the ~/.thunderbird directory to another disk/partition)

I added the various accounts that I receive E-Mail on, UNTIL I tried to add an account with accented characters (Internationalized Domain Names (IDNs)). When Thunderbird refused to accept the domain name I used the punycode version: - An outgoing SMTP server was added to the list but Thunderbird hung when trying to scan the IMAP login parameters.

AND the result was that I had a blank screen when I exited and I was locked into "Unified Folders" mode again - where all this started. . . . .

When I removed the account everything reappeared as before and I can swap between all the folder views.

I can send you the console export but I lost your PM in the reinstall - could you send it to me again please.

I think that we are getting somewhere . . .

Thanks, -Graham-

I've sent you a new private message.
