quite true, but this is Windows ( ;-) )


Anyway, the video driver  is a more likely culprit, but it it is PIL (or
something PIL is calling), and it only crashes after a bunch of calls in
one process, then a major kludge would be to run the grabbing code in a
separate process with the subprocess module. IN any case, it might be
useful to do to debug.

Or, even simpler  write a simple batch file or python script that calls
another pyton script that grabs thte screen, one grab at a time in one
process, but run it a hundreds or times and see what happens.
