Thanks for sending the bug report!

This was indeed a program bug in Fillet in v2 - there would be a crash if you picked 2 points to define a radius distance, and those points were snapped on to the object being filleted.

I've fixed this up for the next beta, but for the moment when you click those 2 points to define a fillet distance, click them off to the side somewhat and don't click them directly on to the object, that should avoid triggering the bug for the moment.

I've also tuned up the crash reporting so that it won't get tangled up with the kind of "fake" Program files directory stuff that Vista so annoyingly added... So in the future the crash report should actually be in the location that MoI thinks it is in and is reported there on that dialog.
