When adjusting the sound level with the keys of my multimedia keyboard, a large speaker pops up in the middle of my screen. It also shows the sound level and that is ok, but is it possible to give this popup another position? The upper right hand corner would be fine, but not in the center of my screen when watching a movie and adjusting the sound... *poof* there is that speaker, not nice..

Found the solution!
left-click the speaker in the systemtray, select mixer -> kmix settings -> switch on-screen-display off.
