		// windows -- such as the script's own main window when activated for the purpose of showing
		// a popup menu -- can be foreground while simulateously being minimized.  This fixes an
		// issue where the mouse will move to the upper-left corner of the screen rather than the
		// intended coordinates (v1.0.17):

	// AutoIt3: Convert our coords to MOUSEEVENTF_ABSOLUTE coords
	// v1.0.21: No actual change was made, but the below comments were added:
	// Jack Horsfield reports that MouseMove works properly on his multi-monitor system which has
	// its secondary display to the right of the primary.  He said that MouseClick is able to click on
	// windows that exist entirely on the secondary display. That's a bit baffling because the below
	// formula should yield a value greater than 65535 when the destination coordinates are to
	// the right of the primary display (due to the fact that GetDesktopWindow() called above yields
	// the rect for the primary display only).  Chances are, mouse_event() in Win2k/XP (and possibly
	// Win98, but that is far more doubtful given some of the things mentioned on MSDN) has been
	// enhanced (undocumented) to support values greater than 65535 (and perhaps even negative by
	// taking advantage of DWORD overflow?)
	aX = ((65535 * aX) / (rect.right - 1)) + 1;
	aY = ((65535 * aY) / (rect.bottom - 1)) + 1;
