When auto refresh is disabled in code, it cannot be turned on again

[freeranger]

My karma config sets autoReload: false as, by default, I do not want it auto refreshing.
I cannot then turn it on again in the UI - clicking "Enable Refresh" changes the local variable reload to true, so the refresh function

            var refresh = function() {
                if (reload) {
                    location.reload(true);
                }
            };

reloads the page, but then shouldReload:

            function shouldReload() {
                if (location.search != null && location.search != undefined && location.search.length > 0)
                    return location.search.substr(1) === 'true' ? true : false;
                else
                    return false;
            };

always returns false because location.search is empty.
Perhaps you should navigate to the page, setting true/false as appropriate?
