The Mouseover Object stores an object reference to the object that is currently highlighted. This reference is cleared in the Cancelhighlight event, but if you attempt to close the form before the cancelhighlight event is called, the erefence will hang. To manually clear the reference, Use

MouseOver1.oCurrentCoolControl = .NULL.
