[osg-users] osgmotionblur error on Mac 10.5.2

[Gerrick Bivins]

Hi all,
I recently tried running osgmotionblur example on my macbook pro and I  
recieved the following error:
OpenGL extension 'GL_ARB_shader_objects' is supported.
OpenGL extension 'GL_ARB_vertex_shader' is supported.
OpenGL extension 'GL_ARB_fragment_shader' is supported.
OpenGL extension 'GL_ARB_shading_language_100' is supported.
OpenGL extension 'GL_EXT_geometry_shader4' is supported.
OpenGL extension 'GL_EXT_gpu_shader4' is supported.
glVersion=2, isGlslSupported=YES, glslLanguageVersion=1.2
OpenGL extension 'GL_ARB_vertex_program' is supported.

This basically renders the model w/o blur. My hardware is:
MacBook Pro Nvidia 8600...latest drivers

Anyone else see something similar on other platforms? Any suggestions  
on what
would be causing problems?
