Re: v7, ViewXY - AccessViolation in DirectX -> BlueScreen
I'm not sure if I understand your question, but the problem was only reproduceable in 32bit (caused by running out of memory). In 64bit, I could not get high enough memory usage to trigger the bug. So I cannot say if 64bit ever was affected or not. But after the fix by Arction, it should not occur a...

Hallo spitzna,
