[solved]Menu bar resizing in Gnome De

[lucamax]

Hello,
I'm using Mint 12 64 bit with Gnome De since a couple of weeks , yesterday while I was trying to get HDMI audio output from my Dell M4400 (impossible since digital hardware is not detected ) I was dealing with Nvidia hardware driver and second screen when after a reboot I found that the menu bar size had increase as you can see in this image
.

How can I resize it to normal dimensions ?

Finally I solved the problem.
To get the panel menu press ALT key + right mouse click .
---> properties
---> Orientation left
The top menu bar was still there and again ALT key + right mouse click ---> delete this panel , (in my case I did it three times)
The I restore the menu bar from left to top position .

For some reason , three empty menu bars were added during Nvidia driver install .

Legend!

The very same happened to me, I have a desktop w/two identical Nvidia cards, huge trouble to get a dual-monitor setup running (and still only in Gnome classic, but I can live with that - different issue). Anyway, in my case it had installed four of these empty panels, due to black background it looked like one huge top panel, and I didn't know how to get at the properties (or, in fact, that it were empty panels at all, and not just black space due to a wrong screen resolution or something).

Thanks a lot for the solution!
