OpenGL 2.0 support, Parallels 5.0, Mac os X on Macbook pro, Win7, Artcam

Attempting to start a CAD program (ArtCam) within Windows 7 under Parallels 5.0... Works fine under BOOTCAMP with Windows 7.

Under Parallels, we get the following message which indicates OpenGL 2.0 isn't fully supported:

Error initialising OpenGL 2.0 rendering. Reverting to pre-OpenGL 2.0 functionality.


How can we receive full OpenGL 2.0 support and is there a newer video driver for Parallels that provides for this support ?

We are on the latest version/release of Parallels 5.0.... Just upgraded and have double checked there are no more updates...

thanks
