A very frustrating experience tonight. I have found W7 to be mostly positive; aside from a sound card issue it's been very stable, but tonight I hit a brick wall.
The first thing my friend said was, "I'd never run W7 in my studio for this reason. Definitely XP."
I do understand that this is circa-2000 hardware, and the company was bought by Apple so I can't really expect them to push their development team to write W7 drivers for it. However, he did spend about $500 on this piece of equipment (and much more on other equipment that is chained through it) so I can understand his feelings.
