If the Aeon Client is opened at a time when no reading rooms are configured for appointments in the Customization Manager, creating a reading room with the Client still open and then attempting to refresh the Client results in the following error:

ERROR AtlasSystems.Aeon.Program - A thread exception has occurred.

A similar error occurs if the Client is opened at a time when one reading room is configured for appointments in the Customization Manager, and that reading room is deleted while the Client is still open:

ERROR AtlasSystems.Aeon.FormMain - Failed to process refresh request.

The Client will need to be closed using the Task Manager when these errors are encountered.
