    texturing problem w/ GLSL shaders

    DKP

      I've got an OpenGL application w/ GLSL shaders, which I have running on a number of systems.  However, when I tried to run it on a laptop w/ ATI Mobility Radeon HD 5800 series card my textures seem to show only the lowest mipmap level.  The geometry is textured, but w/ a constant color.  If I disable shaders, I see the textures fine, so I know the actual texture and coordinate data are good. 

      Has only else seen this kind of behavior?  Is there anything different about the way ATI cards deal w/ texture coordinates in GLSL shaders that I need to be aware of?
