When I right click the tray icon the menu of items pops up. However, as soon as I start moving my mouse over the list of items the whole menu disappears.
I'm running Windows 11.
EDIT: The problem was not observed using a Local Administrator account. It happens with a Standard User account.
I'll try deleting and reinstalling the program (portable edition).
EDIT 2: I'm 99% sure that the incompatibility has to do with an other specific program. I'll investigate.
