I have Win7 x32 on my office desktop PC and recently I bought Microsoft Sculpt Ergonomic Desktop which consists of wireless mice, keyboard and numpad. The communication between these input devices is performed via 2.4GHz transceiver (Microsoft ... v9.0).
So, I plugged transceiver and turned on the devices, Windows started auto-detection and it successed.
However, the keyboard seemed to be "dead", since typing produced no text on the screen (in notepad). So I got the microsoft recommendations list and checked everything. One of my next steps was installing Microsoft software for keyboard and mice management. After reboot, I found an interesting behavior of the keyboard and numpad. When I pushed any button for the first time after reboot - it was okay, everything seemed to be nice (I checked caps, num, tried to type text (first letter was typed)), but only for the first key press.
After first key press several buttons are still functioning: calculator call, volume up/down/mute; but nothing happens when pressing other keys.
I also tested the devices on similiar PC (both DELL Optiplex 390, W7 x32, approximately same uptime) and everything was fine. So I came up with idea that there is some software conflict on my computer... which I don't know how to find and solve.
I will highly appreciate any thoughts on how to solve the problem, or how to diagnoze it.
Thank you beforehand.
