Here is my response from AC today:

Hello Dr. Hayes,

You are correct. This issue is a bug in that version of Amazing Charts. Unfortunately, we do not have a solution for this yet, but a workaround would be to log out of your original PC like you mentioned.

Sorry for any hassles this causes for you and your office.

If you have any questions or concerns, please let me know.
Thanks,

Nick Brochu | Client Services Team Lead

This would have been nice to have it listed in the release notes in the "known issue" section, but it is not.

Hope this helps others.
