' Description:
'   This function sets frmTopMost as always on top of frmParent
'   if iState is True, otherwise resets to normal otherwise.
'
'   NOTE: ensure that any form which is made topmost is
'   unloaded before the Parent form, and that whenever it
'   is unloaded a call is made to this sub to reset the
'   topmost property first.  Otherwise the parent form
'   will retain a bad child form hWnd with possible GPF.
