I ran Secunia Software Inspector and amongst other things it reported real player was insecure and posed a secutity threat so I followed the link and downloaded Realplayer 10.x another was Adobe Reader which I have also updated to Adobe Reader 8. That has fixed the insecurities but now all my music is in realplayer and I cannot remember how to set windows realplayer back as default player also my son cannot now access a network shared music folder could that have anything to do with the changes made when I downloaded realplayer 10. I did a system restore to before downloding realplayer but then I couldn't open any web pages, window opened sying this page is unavailable bla de bla so restored back to after the download and all is fine on the web page issue.
