this problem must be because i am using core graphics
i painted a big red rectangle in drawRect and then went on and called my
core graphics code
the big red rectangle comes up every time
but only after resizing do i see the stuff i draw with core graphics
so i am getting the draw rect events but for some reason i am using core
graphics wrong or didn't set it up right to be used
does this make sense to anybody?
thanks,
bill
