Unreal Tournament and Radeon

I just download a Beta OpenGl.dll from http://unreal.epicgames.com/News.htm to play the compressed textures found on disk2 of UT.
I have a Radeon 64 and these textures kick ass only I crash if I Min. the game back top desktop in Win98SE. Has anyone else tried this dll or these textures?

Try to ask at the Radeon forums at www.rage3d.com
