Try this :

{
WindowPtr windP;

	windP = NewWindow(... with the bounds set the screenBits.bounds...);
	UnionRgn(windP->visRgn,WMgrPort->visRgn,windP->visRgn);

}

In normal windows the visRgn excludes the menubar, but the WMgrPort 
visRgn includes the whole screen. Since the regions are both in global coords,
no problems doing an UnionRgn().
