I've got an Adesso USB numeric keypad for my MBP. The keypad works fine in OSX. The problem is in Win7 in parallels (version 6). In Win7 the keypad functions as if the num lock is not on (up down arrows, but no numbers). This same keypad worked fine with Winxp and a previous version of parallels (version 4). Any clues that might help me figure this out?
