MS 2.0 crashing repeatedly
The piece I'm writing is for orchestra and singers. About an hour ago the application began crashing whenever I tried to change the instrument list (dropping a flute part, for example), or tried to delete measures in a part, or other larger operations. I've rebooted, etc., but to no avail. It's brought the project to a stop.
I've attached the "backtrace.txt" that it produces each time it crashes.
If anyone has any suggestions for solving the problem, or finding a way around this, I'd appreciate if you'd write.
