The point here is that you are trying to replace FrmRemoveObject with
CtlHideControl. Unless I'm mistaken, CtlHideControl basically sets the
'visible' property to false. On the other hand, FrmRemoveObject releases the
memory allocated for that control. And that's why FrmRemoveObject delivers a
memory error and CtlHideControl not. Anyway, that's what I think....
