It's done it on numerous systems, 9600GT, HD7770, Intel Integrated Graphics 256mb edition, just seems to be bad computing on the applications side. For example, renderer is still restarted upon dragging nodes, so I get crashes religiously from organizing. So I have to pause the renderer just to sort things, or forget and wonder why it's locking up. Nothing should trigger the render to restart unless I change shader settings or plug different nodes.
I had mentioned the lag before when were were talking about preview render problems with 3.2.x, including node dragging restarting render. Though I haven't upgraded the demo in awhile. Kinda like when I had TG2 Demo and didn't visit for two years and TG3 came out. Lol
