Has anyone had this problem? It has happened to my twice just today. I play around on my wiz (porting a game), turn it off, and when I go to turn it back on again it gets stuck on the "Qplus" screen, not the "Loading" one the one just before. I have to "update" the firmware just to get it to boot again. Is it a defective wiz? What could be causing it? Any ideas? Anyone experiencing this also?
