Pc crash when closing a full screen renderer on second monitor (projector)

Hello,

On a windows xp 32 machine (latest version) with intel quad core 2.8 GHz, I have a Renderer that I open fullscreen on the second monitor, a video projector (make Optoma) attached to the one graphics card of the machine. I set the resolution of the projector to 1024 x 768, 60 Hz, and check with the inspector that this corresponds to the properties of the Renderer. When I change value of the the fullscreen input pin of the Renderer from 1 to 0, the pc crashes consistently. (Previously I have seen behaviors where only vvvv crashes but this is gone in the latest patch). Any hints how I could troubleshoot this?

Thanks
