Hey guys! I recently started playing WoW on my powerbook G4. Things usually go very smoothly (upgraded to 1 gig of Ram), but lately I have been experiencing sorta regular crashes when playing! They usually come out of nowhere (there is no period of lag or slow loading or anything, it just freezes and quits out of the blue) and happen every 10 or so minutes after a start or restart the game. Any one else having these problems; any ideas?
