Prob with 3D and FS2004

I noticed after installing the new 45.23 3D drivers for my Nvidia 5600 Ultra card (45.23 driver)and e-dimensional glasses that I lost the bumpmapping effects for water. It's possible to change the detail settings for water and land, but it doesn't seem to alter the scenery. It also doesn't seem to matter if 3D is being used, just the presence of the drivers affects it. Once I uninstall the 3D drivers, the water effects return. Has anyone else noticed this? Any ideas or work arounds?Kevin
