Hello, is anybody here using the Sculpt keyboard? I love the keyboard and how it feels, it's a great update for my MS Natural Ergonomic 4000, but... it uses a wireless USB receiver. And that is a major PITA. I've tried all USB slots I have by now, and with all of them it works for a while, and then it suddenly starts missing keystrokes. I installed the IntelliType driver but it doesn't seem to make any difference. I've read that some people suggest a USB extension cable so that the receiver can be as close as possible to the keyboard, but that kinda defeats the whole point of having a wireless keyboard. Why MS didn't decide to use Bluetooth is beyond me. Anyway -- does anybody have experience with this keyboard? Did you have receiver problems? The USB receiver operates at 2.4 GHz -- can that be the source of the problem? (I used to have Magic Mouse problems until I switched my wi-fi to 5 GHz, problems disappeared) Is there some setting somewhere that can help? I really like the keyboard, but the intermittent connection problems are baaaad. (I bought the mouse-less model, as I like my Magic Mouse and don't want a replacement.) Thanks for any response!
