More interpreter crashes

[Steven J. Allen]

Interpreter crashes under Windows2000 while displaying images,
but not under SOLARIS 8.

Application:  Creates 2x3600 lists of 3600 elements, reads 3600 image
objects,
and displays image objects on a TK canvas.

Windows2000
DELL 530
Python 2.1.1

Crashes while displaying 3400th object, was using 1.7GB virtual

UNIX

Any ideas?
