hitTest problem in AS3

In detecting a collision (coins into a pay slot) using either hitTestObject() or hitTestPoint(), after the first collision, the Object/Point becomes mouseEnabled and buttonMode=true. This means that by clicking on the Object/Point the user does not have to “deposit” a coin to make a selection.

I have tried resetting the buttonMode and mouseEnabled to false, with no effect. The coins are dynamically generated, if it makes any difference.
