I have a two month old Macbook Pro 15" 2.0g w/ 1gb ram. I am current on all software updates. I have noticed a lot of hung programs or programs that quit and ask if I want to reopen, report, yada yada. I upgraded to iTunes 7 yesterday and it randomly shut down on me 3 times while just playing music or scrolling through my library. iPhoto has done the same thing, it will hang up while I try to browe my library. I've encourntered great instability with audacity and adium as well. I've had iChat quit on me a dozen times since I bought the computer. I know that Macs aren't perfect, but I have from a troubled past of PC laptops and desktops and I excepted a little bit more stability. I don't think i'm doing anything wrong. I'm not editing any script or anything like that. just movies, music, web, word, etc. Any ideas would be appreciated.
