When I right-click on the googsystray icon, the context menu doesn't go away when I change focus (click on the desktop). I have to choose an option, then cancel to get rid of the context menu.
Pushed to future. This is a GTK bug and there's not much I can do about it at the moment. I have a temporary workaround for the 1.2 tree where the popup will timeout if you mouse out of it, that's the best I can do.
