Since our Thunderbird is version 102.5.x, we have been experiencing a "slow/frozen processing" failure in all Thunderbirds.
New mail arrives, click on the notification that appears in the lower right corner of Windows. Then Thunderbird will not accept any action. Other applications also become slightly sluggish. This also occurs in received mail when switching mail.
It is occurring in both IMAP4 and POP3 and on different mail servers. It also occurs in safe mode, although less frequently.
This occurs regardless of the amount of mail remaining on the mail server.
Attempts to optimize and repair folders do not improve.
I am using Thunderbird on Windows in several different environments and it is happening in all of them.
Is there a workaround for this failure?
