Thunderbird won't open a New Message unless the main window is in focus

[Tim_S]

After updating to Supernova, I can only open a new message (Cmd-N) IF the main Thunderbird window is present. If it is hidden, a new message doesn't open up.

Thunderbird for Mac 115.3.0

Macbook Pro 14-in. 2021 M1 16GB 

Ventura 13.5.2

Thank you,

Tim

Hi @Tim_S, I have the same problem.

Did you find a solution? Otherwise I would suggest to file an issue in Bugzilla.
