The windows program I wrote tends to crash if a person attempts 
to open a couple hundred windows simultaneously.  While this might
not seem like a big deal, I'd rather see everything bomb-proof.

So I pose this question:
I make a request for a given number of pages to getbufr (prodos 8)
if it says it can't give it to me I report the error, 
otherwise I graciously accept the memory.  Could prodos be giving
me memory that is already being used for basic string/variable/program
space?  

My other thought is that since I request pages for the screen image
data, but don't mark these pages used in the bitmap (since they're 
only temporary) that they might be being overwritten by BASIC
or something.

Rational ideas welcome...

P.S.  It may be a few days before I read your replies, our mailer appears
to be down...
