Hello Supporters I'm using Thunderbird build 140.2.1esr. I cannot get it to minimise to the task bar. When I set it to not minimise to the system tray and minimise it, it pops up for <1 second in the task bar then drops down out of sight and reach. Does anyone know the reason for this, please? I recently had to re-build my win 11 (24H2) system and I think it's hapenned since then. I am used to it minimising to the task bar and prefer that. Regards Tony Pickering.
