openGL.dll help

I would like to know how to fix a problum im having with a openGL.dll for a game that i play.
When i play the game in openGL it looks and runs great(better then D3D).The only problum that it does have is some of the colors r a diff. shade.I did notice it has something to do with the lighting ,because if i shoot at the wall that the color has a diff. color shade to it ,it turns to the correct color when the light from the bullit hits it or passes it.So my qusten is how can i fix this?I do not know mutch about makeing drivers and i do not have the sorce code so any help would be great


Is there anyone out there that can help me on this please??
