2143	* Parameters: VOID
2144	* Variables :
2145	* Result : If a pop-up window exists, the return value is TRUE even if the
2146	* pop-up window is completely covered by other windows. Otherwise,
2147	* it is FALSE.
2148	* Remark : AnyPopup is a Windows version 1.x function and is retained for
2149	* compatibility purposes. It is generally not useful.
2150	* Status : UNTESTED STUB
