That is the normal correct behavior for a string gadget, so the user
can go back and make further changes.  The user shouldn't have to be
forced down a linear path through your user-interface.  Let him go back.

The undo buffer holds the contents of the string gadget when the user
began to edit it.

You cannot deactivate a gadget programmatically.  Make sure you aren't
calling ActivateGadget() after you've already closed your window.  That
would put Intuition into a limbo-state.
