2113	* function searches the entire Windows screen, not just the calling
2114	* application's client area.
2115	* Parameters: VOID
2116	* Variables :
2117	* Result : If a pop-up window exists, the return value is TRUE even if the
2118	* pop-up window is completely covered by other windows. Otherwise,
2119	* it is FALSE.
2120	* Remark : AnyPopup is a Windows version 1.x function and is retained for
2121	* compatibility purposes. It is generally not useful.
2122	* Status : UNTESTED STUB
