I have a Late 2008 MBP that I use on location for photo shoots. I added a used 24" LED Cinema Display to allow clients to view images without crowding around the MBP. As I connected the new to me display this afternoon, I tethered the camera and launched a couple applications and it looked great. Everything worked well until I tried to launch CS5.1 and I got an error message "could not launch because of a program error". I looked at the Adobe website and could not find much useful information. Anyone else have this issue when using an external display?
