I have windows XP pro SP2 and a microsoft wireless natural multimedia keyboard. my issue is that sometimes when using the multimedia keys, specifically the play/pause buttons and the track forward and backward buttons it will occasionally "hit the button tiwce" for instance if i hit the pause button it will pause for a spit seccond and then resume playing, also if i hit track forward, it will advance two tracks insted of one. this mainly happens with iTunes. has anyone else experienced this?
