Additional Information

After detecting a valid mouse click (when the mouse is pointing to a control area on a window), a process needs to call SS.MnSel. This calls tells the enhanced window interface to handle any menu selection being made. If accumulator A returns with 0, then no selection has been made. The calling process needs to test and handle other returned values.
A condition where Register A returns a valid menu ID number and Register B returns 0 signals the selection of a menu with no items. The application can now take over and do a special graphics pull down of its own. The menu title remains highlighted until the application calls the SS.UMBar SetStat to update the menu bar.
The support module for this call is WindInt.
