  15. You can use imsg->IDCMPWindow to tell which window dispatch function
  16. to go to.  This is by far the easiest.  I.e.
  17.  
  18.     while( 1 )
  19.     {
  20.         got = Wait( mask );
  21.         while( imsg = GetMsg( windowport ) )
  22.         {
  23.             if( imsg->IDCMPWindow == OptsWnd )
  24.                 OptsEvent( imsg );
  25.             else if( imsg->IDCMPWindow == MainWnd )
  26.                 MainEvent( imsg );
  27.             else if( imsg->IDCMPWindow == PrefsWnd )
  28.                 PrefsEvent( imsg );
  29.             else
  30.                 Oops bad IDCMP...
  31.  
  32.             ReplyMsg( imsg );
  33.         }
  34.     }
