	//ButtonOption button;

	DrawingDraw dd(63, 187);
	dd.DrawImage(0,0,IMG::silo_small);

	static Size ppi(72,72);// = ScreenDraw(true).GetPixelsPerInch();
	QtfRichObject qrdd(CreateDrawingObject(dd.GetResult(), Size(63*ppi.cx/10, 187*ppi.cy/10), Size(63*ppi.cx/10, 187*ppi.cy/10)));

	//setup button label
	button.SetRect(x,y,116,300);
	String qtf;
	qtf << qrdd;
	
	PromptOK(qtf); // <<-- works perfectly
	
	qtf.Insert(0, '\1');
	button.SetLabel(qtf); // <<-- causes no run-time error itself, but app crashes on painting this button

I've noticed that in case of drawing Image inside Prompt-dialog, image is painted with noticable delay (about 100-200 milliseconds). May be it is somehow interconnected with painting button error...

P.S. The image is painted on white background, while it is semi-transparent itself. Is there a way to paint it using transparent background?
