Comment 3 for bug 772995

The same for me. When I run any systray application (skype, gnote, etc), menus of all indicator apps left side from the clock appear not accessible by left click until I close the systray application. It also happens when I run a caffeine indicator app.
I have a default set of indicators + keyboard layout and dropbox.
But I have no problems with the indicator apps menus on a standard gnome-panel in the 'classic ubuntu' session, so I guess the problem may be related to the unity panel.
