I've installed Thunderbird and FireTray addon, then checked to minimize to tray on close. Now, if I start Thunderbird after quitting (Win+Q) and try to close with Alt+f4:

  • for the first time it's minimised properly to tray
  • on each next time I need to double press "close button", and if the window is not maximised
  • firstly it maximizes (first Alt+f4), then closes(second Alt+f4)

Could you help me, please?

Ubuntu 11.10, Unity 2d

I was having a similar problem in that I would lose the menu after opening and closing Thunderbird a few times whenever Minimize to Tray Revived was activated.

A workaround was to actually disable Global Menu Bar Integration. Then you use Thunderbird's native menu when Minimize to Tray crashes Unity's.


it behaves in an odd fashion for me in Unity (normal, compiz version). Basically I don't think it plays nice with Unity as things stand. It also loses its global menu after several open/close cycles.
