I was working on a 300 dpi drawing. Had two layers, one background and one with just some lineart on it. It was lagging so I thought I would change the canvas size to just big enough to accomodate the deer I was drawing.
When I chose resize canvas the program made a nice clean crash to desktop, with report to Microsoft and everything, which I sent. I opened the image again and tried it again. Exactly the same thing. Sent that report too.
The resolution of the painting is 5334*3216. I had one reference image open.
