Thank you all for your replies.

So far as I follow you not only the realtime view in Poser uses the GPU+OpenGL but also other functions inside the application rely to some degree on it. I wasn't certain about the connection between switching rooms, rendering and GPU capabilities. 

I'll checked some weeks ago Intels website for drivers, I'm going to recheck today. I doubt there's one but I hope it is.

@wimvdb: Do those problems always happen - even when you use default Andy (render, material room and unresponsiveness)? And if you turn off OpenGL? Or does it only happen when scenes are getting large?

They are unpredictable, only some of the crashes I can reproduce. With Andy and simple, plain shaders I can switch to the material room. With more advanced shaders and JamesG2, Alyson I get into trouble. I just retried now with SreeD to switch to the material room with a scene with which I got recently trouble - it worked, but know it also works suddenly with OpenGL. 

Usually I make small scenes with at most 200k polygons (1 Model and/or some props), but I'm using a lot of shader capabilities, like fast scattering, fresnel and ambient occlusion (when it works).

@aeilkema: I thought so that an HD3000 GPU will get me into trouble. With other 3D applications I don't have such problems. DAZ Studio 3 and 4, Carrara, Shade 12, Vue are running without trouble.

@vilters: [...] Download , install, and run Advanced system care [...] What anti virus are you running?

I'll try this advanced system care, though I never heared of it. Curious about it. I running russian anti virus application. Kaspersky Anti Virus 2012, no security suite only the scanner. I'll try to run Poser without KAV sitting in the background.

Hell, you ran Poser on a netbook? That leaves me with hope to solve my issues.
