glCreateShaderObjectARB( GL_FRAGMENT_SHADER_ARB ); crashes !

Question

Hello there,

I have an iMac with ATI Radeon 2600HD which supports Fragment_shader_arb. But whenever I use that function, it crashes the program. Ironically, it works on a windows installation in the same machine without any problems. I'm running OS X 10.6.2;

Can anyone please help me out!

P.S. Vertex shaders work fine without any problem.

Thank you!
