This is a very minor issue, but if you launch Canary Admin a little too early (ie. while the Canary services are still starting), you end up in a window with greyed-out panes and a red error message at the top.

There's unfortunately nothing you seem to be able to do at that point - the app simply dead-ends. It's still 'working' (still responds to Windows messages), but there's literally nothing to do and no in-app method of resolving the issue.

It would be nice if there was some form of 'refresh' button so that you don't have to close and re-open the application, or even just a prompt to close the window.
