Source code for two screensavers and an application are available at
http://bersearch.com/PrivateTechSupport/Circles/crashingpolygon.zip
One screensaver shows several polygons that crash -{NSBezierPath stroke. The
other screensaver generates and maintains random polygons. Within 5 - 30
minutes one of the randomly generated polygons will crash -stroke. The
application attempts to use the same polygons to crash -stroke; these
polygons do _not_ crash -stroke from within the application.
Thanks again.
