Using Thunderbird 52.3.0 on Windows 10.
My Thunderbird installation includes three AOL Imap accounts. One of them, inexplicably, no longer connects. (I get the "Enter Password" dialog, followed by "Login to server imap.aol.com failed".) I didn't change anything, I'm sure; the three accounts all have the same settings. (And the same password, too.)
I tried adding the account again; it tells me the password is wrong. (It's not; I checked by logging in to the webmail site.)
Is reinstalling Thunderbird a good way to handle this?
(I'm hoping that doing so will fix another problem too: You know the popup notification box when you have new incoming mail? Sometimes it won't close when clicked.)
