GMail IMAP account.

Says needs to enter password.
I do and it rejects it.

Other GMail accounts work fine on this PC with TBird.

Went to a different PC and that one woks with that GMail account.

I dumped the passwords and I am using the password that shows in the dump.
The password is as expectd.

So why is TBird rejecting my password.
CAPS LOCK was off !

Other PC with this account shows notice from GMail of attempted access.
