There have been numerous security-related changes in XP. The WM_CHAR has wonderful
security implications, and they may have deliberately broken this feature. It would make
sense to (actually, it would make more sense to not allow system-wide message hooks, but
only if security matters. If it doesn't, which is the current design, then it doesn't
matter. The ability to intercept messages should be a securable feature, or better)
