I just successfully installed Boot Camp 2.0 with WinXP Home SP2 on my new Santa Rosa MacBook 2.2 GHz. Everything is working properly as far as I can tell, except Fn Delete key combination is non-functional in Windows. All the other advertised Boot Camp key combinations work that I've tried (for example, Fn Return emulates the Insert key), but there seems to be no way to do a "normal" Windows forward delete in Boot Camp, which is very annoying.
I'm not the first person to have run into this problem, but it seems to vary on different systems; see:
Keyboard Shortcuts don't work in XP (boot camp) - Mac Forums
Any suggestions? Should this bug be reported to Apple directly, and if so, where's the best place to do that?
