r75402 is affected. r75402-winamp.png
The secret tab in taskbar is not shown when executing Winamp on Windows.
Winamp classic skin and Bentoo skin - both are affected the same way.
I thought it might be rewarding for us to fix this popular app, because Winamp 5.666 development is freezed and no moving target anymore.
This is a very old and known bug (down to at least ros 0.4.0rel), but I could not find existing ticket for it.
