Ah, thanks. I'll give it a go tomorrow. I'm just about to leave the office.

(Just to be clear: I'm not 100% sure that the setAlphaBufferSize(0)
thing is what is causing me trouble on Win 7 at the moment, since I've
made other changes as well. The problem I'm having on Win 7 now is
that our volume rendering is not showing up, but it may be caused by
other things.)
