Sorry - this is bad writting on my part I meant to say "In the same manner that when erasing a file the Mac doesn't overwrite all that disk memory space with zero, when you quit an app in memory, the mac doesn't set those memory bytes to zero." Hope this clears things up. As it's horrible getting seemingly contradictory info from the list. jonathan ------------------------------------------------------------- !
