Multiple blank taskbars

[Elmer Fudd]

When I boot to GNOME Classic, I get four blank upper taskbars (pic attached).
There is no obvious (to me) way to delete them.

Unity Desktop works fine - just happens in Gnome desktop.
Worked before (this is my normal environment). After trying to config a second monitor, these extra taskbars appeared.

Anybody know which file I need to edit to get rid of them.

I have deleted all the NVIDIA drivers and re-installed the latest 295.20

thanks.

11.10 3.0.0-16
Sony Vaio
Gnome 3.2.1
NVidia 425M driver 295.20

Have you already tried doing Alt+Right-Click or Super+Alt+Right-Click, respectively, and then choosing "Delete this Panel", for the excess panels!?

Regards.

I didn't try the Alt.
I figured that since there were no other posts on this problem that it would be simple.
Thanks.
