When I was watching a video , and /or listening to streaming music
if I used my multimedia key button to raise / lower the volume this volume button got stuck in top - most mode (it was very large) and I could not close it or get rid of it .. it was taking  up  resources and... the whole screen was flashing and especially when I mouse'd over the main menue, I Found it VERY difficult to select anything from the main menu , and this volume button, whatever it was was quite difficult to close... and I also had some application failures which occured allmost simultaniusly...
