I was wrong. It was not the painting holding the TThread. After I removed 
those lines drawing on PaintBox it's still the same problem. So, it must be 
those graphic operations (which is not running in the same thread)  :-(

Now, I use TTimer instead of timeSetEvent(). The music is playing properly. 
Of course TTimer is less precise. In my case, I can accept a little bit 
delay in the graphic (have no choice).

Any suggestion to optimize the graphic routine? BTW, some Copy operations 
are doing outline the text. Is there a font property doing that?
