Hi Folks! My month-old iMac (with the QC upgrade and 8 megs of RAM (2 in use) crashed last night for the first time. I had just installed Google Earth and was switching between several screen display sizes (e.g. 1024 x 768) when I suddenly got a blue screen and was booted to a logon page with my accounts listed. After I selected my account, entered the password, etc. everything ran fine again. I'm hoping the crash was just because I tried 3-4 different screen sizes within a minute or two. Or, should I be worried?
