I've got a strange problem on my hands, not quite sure what to make of
it, hoping someone else has run into this or can give me a suggesting
on where to go next.
The problem is I have a subclass of NSTextView (i've overridden mouse
down, but not any of the draw methods) where the contents seem to get
"smudged" when it's enclosing scroll view is scrolled.
Here are a few screen shots of the "smudge".

Also I can't duplicate this problem on my own computer, but the
computer that it's showing up on has these specs:
"I have a 1.25 Ghz dual processor G4 tower with 2GB RAM and Apple
Cinema HD display being run by whatever video card came with the
machine. Apple system profiler says "ATY, RV250" for the card model and
it contains 64MB or video memory"
I really have no idea where to look on this one, it doesn't look like
any graphics errors that I've seen before. The NSTextStorage that the
text view is drawing is my own custom subclass, but it seems to work on
all computer that I've tried without problem so i don't think that's
the cause.
Ideas?
Thanks,
Jesse
