Extending the form?

It appears as though its a problem with Reader, but Im yet to hear if this is consistent.Also, would there be a problem with digital signatures? We have contractors that roll on and off frequently, and therefore thier signatures are revoked...can this create problems for our forms?

I dont know if this is going to be a bit of a broad question, but we have some LiveCycle v8.0 developed forms which are distributed out to various people for completetion and sign-off. We have encountered an issue with one form that some people can and cant save. There seems to be no reasoning as so...
