Just started with windows 7 coming from XP (same PC, fresh install of Win 7)
I've had my USB Microsoft Wirless multimedia keyboard and mouse for a few years now and it has never let me down.
I have not installed any specific drivers for it, on Windows 7 it was working from the off so i left it at that.
But on two occasions, although the multi-media keys still work (open explorer, email, volume etc) the alpha and numeric keys stop working. Windows gives me a "dink" sound when i press them but nothing actually types in a search field or whatever. (in fact for some keypresses other things or messages start popping up from IE8 for example like the key mapping has gone crazy).
On the first occasion this happened i was installing a game (Call of duty world at war 2) and noticed the problem after the install had finished.
The second time I was ripping a Blu-ray to my HDD with CLown_BD, ANYDVDHD etc.
Although I didn't realise it at first, the mouse has also been playing up in the form of not working when i double click to open a file, instead it opened a properties ********
Only a re-start cures these issues when they happen.
I've checked the batteries so its not that.
Checked microsoft updates relative- no joy.
Checked the "update driver", but windows found no better driver than the one being used.
