Disabling the winamp overlay?

[ugginat0R]

This has been driving me crazy for the last year, and after googling a massive amount of pages with no answer I decided I'd ask here. I apologize if it's something silly, but I can't locate it in the settings.

How the hell do you disable this:
(the overlay that contains 'end of playback' and names of next tracks etc.

Much obliged
