I have 2 POSX touchscreen monitors and have had no problems until this past week when I changed one out for a VGA Monitor. I had issues with that monitor, made some changes to the monitor arrangement menu, but then decided to go back to the touchscreen instead of the VGA monitor. Now when I touch one screen, it has its affect on the other screen (i.e.- I touch somewhere on the Cue List screen, and a channel tombstone lights up as if I had touched that screen). I've seen a post about this in the past but can't put my finger on it now. I'm running Ion v1.9.
