Vray light invisible in viewport!!!

[orei]

Hi my friends.. i'm a noob of 3dstudio max 2009 with vray.. i've a problem.. with my radeon mobile 9000 video card, in the direct x coniguration, if the default light are deactivated.. and i use vray light, i can't see any light preview in viewport.. but the light appair correctly if render the scene.

 

If i use vray sun instead of vray light.. i can see the light in the viewport!!

 

I tried to use different catalyst driver.. but nothing happened..

 

If i use Opengl configuration.. everithing is ok.. but the work is too slow..

 

How can solve this??

 

Thanks a lot

no.. i can make the vray light... the rectangular, the ies, and the sunlight.. in the render.. all those three type of light work correctly.. the problem.. is for the vray rectangular light.. in the viewport.. that make me all black, and not light the scene.. but in the render is ok!!

 

thanks
