WGL_ARB_create_context

Hi, I try to create an OpenGL 3.1 forward compatible rendering context with wglCreateContextAttribsARB.

I use this tokens :

  WGL_CONTEXT_MAJOR_VERSION_ARB, 1,

  WGL_CONTEXT_MINOR_VERSION_ARB, 0,

  WGL_CONTEXT_FLAGS_ARB,

because my application  is written in OpenGL 1.1.

With the last version of the driver I dont get error but the context in not created and nothingis drawn..with the old version works fine but when I try to activate the HiddenLine then application crash in atioglxx.dll ( I suppose glPolygonOffset is the problem )

With other graphics card everything works fine.

Can anyone give mea hint?

Thanks in advance.

Best regards
