Just received my 13" MBA with an i7 processor. XP is very, very fast. However, I had a problem where I would get blocks of black on the screen sometimes flickering or staying around for a few seconds. This was only in full screen mode from what I can tell. What was even more of a quandary was that when I shut down XP and rebooted the MBA, I went back into Parallels and the problem seemed to go away. I did not have this issue on my older MBA. Maybe this was a one-time thing, but I am concerned about is I cannot afford for this to happen again. Any thoughts?
