That's what I had set up before I installed 7. 7 Decided I must have meant PCL when I said PS, and switched it without telling me. Hence the hassle. It's fixed now.
Probably just a side-effect of updated drivers. PCL is more common, after all, so the hardware wizard (or whatever they're calling it now) went with that first. I end up with a similar situation at home every time a new graphics driver is released, as I usually get it from the manuf. about two weeks before it shows up on Windows Update, but WU always asks anyway
