Fatal Error

Can anybody help me with my problem.

I can compile and run any simple 2d Cascade example (which names begins with 01_*) but when I try to run other examples (e.g. 04_*) I have message "Fatal Error During Graphic Initialisation".

I set environment variable CSF_GraphicShr to the location of OpenGL library (tried both one supplied by Cascade distributive and one from WinNT), but it does not works.
