Query: Works on MacBook/Parallels

I use this mouse/keypad combo on my new MacBook, which works great in MacOSX immediately. I mainly use the keypad in Windows XP/Excel whie running Parallels software. Had a bit of trouble figuring out the configs to get the NumLock function to work correctly in Windows, but fixed the problem and it works just fine.Pros: Works in both Windows and MasOS.Cons: Not Bluetooth. Keypad is enormous.Overall, a good buy so far
