I am looking for an easy way to solve the problem of people not 
realizing that they cannot save unless they click "Enable Updates". 
There are 30 save buttons in setup and adding a message box and logic to 
each is more work and more risk of screw-ups. Adding the extra message 
on the screen is easy.

Options for making setup changes without backend restart:

If you enable updates while a recording is in progress it will not stop 
the recording, but other recordings will not start. Note that next to 
the "enable updates" button it displays the details of the next 
recording, or one in progress, to help you decide.

- You could enable updates, make the changes, then remember to restart 
after the recording is finished.

- You could enable updates, make the changes, then run a command that 
will enable recordings again without a restart (potentially dangerous):

   curl -X POST "http://backend:6544/Myth/ManageScheduler?Enable=true"

- I could add a button somewhere with warnings that enables updates 
without disabling recordings (potentially dangerous)

- I could add a button somewhere with warnings that enables recordings 
after updates, without a restart (potentially dangerous)

These scenarios have not been tested.
