I just bought a Targus USB numeric keypad (the corded one without built-in calculator, but with a 2-port USB hub) for my MBP. Plugged it in, OSX (10.4) recognized it as a keyboard but couldn't figure out the type since it was a keypad not full keyboard, but it works... almost. The thing is, if I turn off its own numlock, then it works fine--the arrow and page up/down keys work as expected. And when I try to type numbers I do get numbers... but it is apparently registering several "clear" keystrokes along with the number I pressed. End result it's useless in Calculator (or the widget) since it hits clear after every number so you can't input anything, and while I can input numbers into a text document the extraneous "clear"s slow it down and make annoying beeping (since there's no defined action for that key in, say, TextEdit). I tried it in all three keyboard styles available (ANSI, ISO, and JIC), but the behavior is identical. Anybody have an idea if this is just a bum keypad or if it's actually not Mac compatible for some reason? If anybody is wondering why I picked this particular one, it was because I had a $10 off coupon for Staples and I can't use the "embedded" one very efficiently; the two cheap ones they had was this Targus and a bright blue mini GE dealybob with retractable cord that was uglier than the Targus and would be harder to use on account of smaller keys. Targus didn't mention Mac compatibility and the GE did, but I figured "Hey, it's a numeric keypad--surely they're all the same". Was I wrong? Targus's website help is pretty much useless.
