My ComboV project crashes AU Lab 2.1 when switching to Generic View. I have also tested Schwa's Olga in AU Lab, and that also crashes. The cause is that mouseMoved, mouseDown etc. in IGraphicsCocoa.mm are being called while mGraphics is NULL. A solution is to check mGraphics in mouseMoved etc.: Code:

Thanks, I noticed this problem too. Nice how you can switch views in au lab.

still seems to be a problem if you move a control after switching from cocoa to carbon and back to cocoa

I have nothing technical to add, but I'm very glad your fixing this stuff, and if you're ever in Lisbon, I'll buy you a beer!
