Too much ado... I'll probably tell the customer I can't do it. Guess I can afford it in this case. It was worth spending two days of Christmas holidays for it, but not more.

And still I'm sure there must be some windows event. I've seen somewhere the C++ Code that catched the windows redraw-event on the list, but it was too much of a science for me.
