Pressing the hyphen key brings up a volume control bar across bottom of screen. Star key brings up large speaker icon in top right hand corner of screen. This started after I had deleted some software, installed service pack 3 (since deleted). I have a partitioned Hard drive with win 7 on one and xp on the other. The above affects xp only. All keys work as normal in win 7. I have tried other keyboards and all the same. So its not the keyboard but some setting gone wrong somewhere. It is set to UK keyboard. 1 person needs an answerI do too
