Hi - I've been running MC7 on my Imac forever, with a second monitor. Suddenly, the center of the center monitor is dead to Avid. Clicking does nothing. If I pull the bin to the corner of the monitor, everything works fine. If I put a non-Avid file in the 'dead spot' of the monitor, everything works fine, so it's not the monitor. The center of the second monitor is dead to Avid only. Has anyone ever experienced this? Nothing seems to work to fix it.
