When trying to playing "The Elder Scrolls III: Tribunal" version
1.4.1313 german I get now the following fixme's:

fixme:d3d:IDirect3DDevice8Impl_LightEnable Light enabled requested but light not defined, so defining one!

Now the cone's of the lights are visible on surfaces near a
source. Looks better now, but the known issues (body texture missing,
crash after a while) still persists.
