I did a search but could not find anything similar on this forum. Since upgrading to 10.6.5 I've been experiencing something strange. Three separate times while trying to load media full screen, the computer will hesitate for a moment then log me out, no warning. The first incident occurred when I was loading an embedded flash video. I clicked "full screen" and the comp brought up the first video frame, hung there, then logged out. This happened later with a different video. The third incident happened today when I was loading some photos in a slide show in Bridge CS4. The first image came up full screen all scrambled then the comp logged out. All incidents have happened while trying to load media fill screen and while being connected to an external display. Any thoughts?
