a quik ? about smoke domains

I am having a problem with the smoke domain. I have tried it in 2.65 and 2.66 and have the same problem.
I set up the cube for a domain, set the display type to wire and all is fine.


then as soon as I move my mouse to zoom, rotate. what ever. it goes black.


the smoke/fire simulation still works inside the black domain. set the domain not to render and it works like its supposed too.
But then you cant render any of the textures you set up for your smoke domain.
If I set the domain to render and move my camera inside the domain it renders fine. but my scene is still inside a black box.
Im using an acer laptop with dual core intell and 4 gig of ram. any help on this matter woulld be greatly appricated.
