  21.         the spots is:
  22.  
  23.         nHandle := twBRHotSpot( nT, nL, nB, nR, bAction, ;
  24.                                 nButton, nPause, lRelease )
  25.  
  26.         Where: nT, nL, nB, nR - Absolute Screen
  27.                                 coordinates of
  28.                                 Hot Spot.

  32.                                   0 = left
  33.                                   1 = right
  34.                                   3 = both
  35.                        nPause - Default delay time
  36.                                 for mouse action.
  37.                      lRelease - Default release
  38.                                 time for double
  39.                                 clicks.
