I'm having problems with the XFCE top panel in Ubuntu Studio 12.04. Several times a day when I click on the open tabs, nothing happens and the right hand side log out/shut down menu also is gone. I have to do a hard reboot. Rebooting restores the panel.
I've just been investigating the Panel Preferences and see that there are two panels. I have just deleted one of them so I now have just the one.
Any suggestion gratefully received
