I have a Microsoft Wireless Desktop Elite Keyboard and the Wireless IntelliMouse Explorer 2.0 combo. When i bought it, it was refurbished. The problem is, when I type anything, sometimes the key i last press would seem to get stuck. Not physically stuck, but whatever the key does will get repeated up to soomething like 20 times. For example, if i press the space key last, it will output 20 spaces. It gets really annoying when i open a file with the enter key and it happens. It doens't happen ALL the time, but it happens enough to annoy me. I have tried reinstalling the proper drivers, using the PS2 adapter to connect the keyboard to a PS2 port. I've also formatted several times (not because of the keyboard) but the problem never goes away. Is the keyboard busted?
