I purchased the Microsoft Wireless MultiMedia Keyborad 1.0A and the Microsoft Wireless Optical Mouse package 12/03, and absolutely love the freedom it gives me.  Lately however, the keyboard does not respond properly when I DEPRESS the keys.  I must constantly move the keyboard to a different location (for instance, on my lap) to get the keys to work.  I put in fresh Duracell Coppertop AA batteries, but the results did not change.  Both the mouse and keyboard sit on top of my desk, with the mouse to the right of the keyboard.  The tramsmitter, which connects to the computer via USB wire, sits under the desk.  The mouse works fine.  This setup has not changed since 12/03.  Since I do a considerable amount of input via the keyboard, this is a major inconvenience.  Could the keyboard itself be the problem?  Any suggestions for resolving this problem?

OS is WinXP Home with Service PACK 2, PIII 1.2G, 512mb, 80G & 20G HD.Are you sure that the software needed for the keyboard is installed and compatible?

[glb]Flame[/glb]YES - the CURRENT Driver Version is 2.20.447.0 Dated 3/21/02.  This is the latest driver that I can find for the keyboard.  The Keyboard functioned fine until just recently.Try moving the transmitter/receiver on top of the desk and resetting it with the connect button on the transmitter.

I use several wireless setups at various places and they all can get a bit flaky at times.  If you have moved another wireless setup somewhere near it the you may get interference from that.  If you have added another electrical device on or near your desk it could interfer.  I have even seen the signal degrade by filling up the paper click tray in the drawer just above the transmitter.
