I want to send a bug report to ATI ...

but I’m not subscripted to the developer programme. I have a complete description of the problem, including OS, driver version, circumstances and a short glut-based demo application.

What should I do next?

Try posting the problem here in the beginners forum.
And let some people look at it.

If it´s a serious problem, post it again in the advanced forum and say, that you have an ATI bug or something similar in the topic.
I´m pretty sure, that an OGL engineer from ATI will read it and give you his e-mail address or try to solve the problem via communication on this message board.

There are quite a few ATI engineers on this board, so that shouldn´t be to much of a problem .

Thanks for the reply, as you may see I’ve already fired away my complete material to the advanced forum. I believe it’s quite bullet proof
