--- Comment #8 from Frank eekfrank@hotmail.com 2008-04-10 16:26:38 --- I gave a shot at editing my context.c , so now there are five lines that look like this:
/*checkGLcall("glEnable(GL_FRAGMENT_SHADER_ATI)");*/
That compiles and runs ok, but I still have the corrupted graphics, so I'm either getting too much or too little with the comment trick.. I don't know..
