XMonad: un-removable gray windows at startup

[sharshofski]

I just upgraded my netbook to 12.04 and decided it would be fun to try XMonad. I'm running XMonad + GNOME. Everything works great out of the box... except...

Three panels appear at startup: the desktop and two gray panels (as shown on the right in the screenshot). I can't remove/close the two gray panels with ctrl+shift+c. And I can't fill them with applications/windows. So they're just pointless. Why?? What am I doing wrong? How can I get rid of them? Augh!

I've been moving the two gray panels to another workspace and ignoring them, but I'd rather understand what's going on.

Any help appreciated!

Post your xmonad.hs

I just grabbed one of the templates from the XMonad site to start with. I couldn't find anything in there that seemed related.

I figured out part of why the gray panels showed up: I selected the "GNOME and XMonad" option at login. When I run

pkill gnome-panel

the two gray panels disappear. And running

gnome-panel &

brings them back. So clearly GNOME and XMonad aren't meshing well at startup. Does anyone know why this is happening in the first place?
