Description

While clicking around the webui making sure everything works for the Knox integration, I discovered a bug where manually refreshing a page when auto-refresh is turned off leaves the auto-refresh checkbox unchecked but turns auto-refresh back on, as we don't check the value of the checkbox on page load but always just start with auto-refresh on.

When this happens, it actually makes it very difficult to turn auto-refresh back off, since if you check and then uncheck the box, it will start and then stop a new refresh interval while leaving the interval that was started on page load running. The workaround would be to check the box, manually refresh the page again, and then uncheck it (or navigate away from the page and then go back)

The fix is probably to check the value of the checkbox on page load and disable auto-refresh if its unchecked.
