Hi,
Since updating to Thunderbird 140.7.1esr (64-bit) on Windows 11, moving messages from Inbox to any folder takes about 7 seconds.
Details:
Account type: IMAP (Cogeco)
Happens in all folders
Inbox has ~600 messages (not large)
Was working normally before the recent update
Delay occurs every time moving a message from Inbox to another folder
No freezing — just a delay before the move completes
No antivirus changes
Issue started immediately after update
This appears to be related to IMAP sync behavior introduced in 140.x.
Has anyone else reported this, or is there a known regression?
Thank you.
