I have had a lot of crashing problems with my MBP, and they only seem to get worse. Using any progs that use the video card with any intensity causes freezing screens, insanely hot areas between the keyboard and screen and, occasionally, the Transparent Grey Screen of Death. Specifically, I have the most problems when backing up and compressing movies using Toast Titanium, when using iTunes or Front Row with album art, and Age of Empires III (which is when I get the Trans. Grey Screen o' Death). My most recent crashes, I was compressing a movie in Toast and updating some files in my iTunes library. I slowed to a c r a w l , got HOT, and then my toolbar flipped out! (image below, enlarged to show detail): Will the 10.5.3 update fix this problem? Anyone else have the same BS?
