There might be an easy solution for this, but I haven't found it yet.. I've got a 24" iMac, and run the dock on the left hand side of the screen. After hooking up a 15" Wacom Cintiq , everything works fine - except for the fact that the dock now resides on the left side of the Cintiq's screen. Is there a way to set the iMac as the main monitor, so the dock with stay on it instead? Any help would be appreciated, thanks!
