Hi Taj,
"runs fine" in this case means it hasn't crashed, remains responsive, but nothing is displayed, not even briefly. Screen mode is set, but the screen stays black. I've filed a bug report with ATI.
Don't waste your time on trying to fix it for me, there's either something wrong with my PC specifically, ATI Vista drivers specifically, Vista specifcally, or the X1600 specifically, or the code. I don't fancy debugging that lot frankly.
Nino, it's probably not Vista, it's probably something local to my setup. There's no way ATI would release drivers with a regression like this.
