Wireless keyboard - strange behaviour
We have a Microsoft USB Dual Receiver Wireless Keyboard. It's been a great thing to have - easily repositioned to suit different users and with useful hotkeys. However, yesterday it started behaving strangely. At first, it was missing out some of the letters typed. It didn't want to put exclamation marks or the number 2, for example. Gradually, the problem got worse: every third or fourth keystroke needed to be made five or six times before anything appeared on the screen. It wasn't one of those 'delayed reaction' incidents you get when the computer's trying to do something else in the background, it just didn't happen. Then, the 'sleep' hotkey refused to work at all.
I turned the machine off completely overnight. This morning, the characters appearing on the screen bore no relation to the keys pressed on the keyboard and were, in fact, completely random. We put the machine to sleep, woke it up again and suddenly we were back to normal.
The only thing that happened before the problem was an upgrade of Firefox.
If anybody has any thoughts on what may have happened here, I'd be grateful for a hint, just in case it happens again.
