Mission control was working fine until today. I was testing out the desktops feature when I realized i couldn't delete any of them. I now have about 10 desktops open that I can't delete. The little "X" that normally appears is not there! Is there any way to reset mission control or force close the desktops. Logging out, restarting, shutting down, none of them work, even with the " restore windows when quitting and re-opening apps " box UN checked in the options. Please help, thanks!
