Using latest release of AlphaSkins, Delphi 2010, Windows7 x64.
The problem I'm having is with TsTrackBar component.
The component turns into a black rectangle on the 1st mouse down event when it is not in focus and gets focus. As soon as you move the mouse, release the mouse button, etc. the component repaints and looks normal.
Here is the trackbar, it does not have focus.
Thumb has changed color because cursor is over trackbar thumb.

Click on the component but do not release mouse button or move the mouse cursor.

If you move mouse or release button component will repaint and because it now has focus will not turn black again unless it looses focus. If it looses focus blackout behavior repeats.
Here's a demo of the problem w/source.
