What the heck is that? Out of the clear blue sky, I'm watchin TV, and my 522 stops, an starts doing a "system integrity check". At least I think thats what it said. Thank god I wasn't really into what I was watching....I wanted to post right away but the forum was down this morning. It also said "this will take up to 10 mins". It took about 5 or 6 and I wasn't to disturb the 522 while it was doing its thing. I thought I had seen everything.
