Michael,
This happened while I was trying to extrude a height map using Max's v0.6 script.
Perhaps ran out of memory.
Crash dialog is attached.
No crash report location shown and "E-mail crash report" seemed to do nothing.
If you can tell me where the crash report is likely to be (if it is likely to exist) I'll happily email it to bugs@moi3d.com
Mike.
