TBS creashs on undo

When I am using the paint tool in the tutorial Painting_Rough, when I hit apple-z for undo, it crashes the program. I am using MacOS 10.4.10.

Any ideas?

Hi Patrick,

I was just wondering, is it when you paint or when you use the paint all feature (Alt+Shift)?

Is the software crashing after a specific step in the tutorial?

Best regards,
