OK, I've given up trying to get GE to work in DirectX mode for a Mobility Radeon 7500 card.... can't seem to find newer drivers that work, soooooo

I have it set to default to OpenGL for the user but every time they open it it "recommends" using DirectX.

I searched here and looked through the options and struck out.

How do I get it to quit prompting him to use directX?
