I vaguely recollect a similar topic, possibly yours (I searched though your 110 posts at the Rendo Forum, but cannot find it).

In my case SuperFly / CUDA crashes. Windows is fine. Poser needs to be restarted, otherwise SuperFly keeps producing a grey square.

It seems some of the shaders makes CUDA unhappy, but cannot nail it due to apparent randomness of the isuue.

Are you telling me you have encountered exactly same issues and have already filed a ticket? Did you get any response from Bondware yet?
