Don't know about C3, but certainly in C2 that is an issue. Don't recall how to fix it but I think you are looking at the right issue. You've either got to clean up after you are done or reset things properly when you use it again. You've got a setup() method to work with so that seems the place to start, since adding a new finis() (or whatever) method to cleanup after you are done would obviously have much broader implications...
