Odd because it never behaved that way before. It seems to be doing as you indicate – taking quite a while to load one of the tabs, but after it’s been loaded in the browser, I can switch back to it from another tab quickly.
I didn’t run any updates or change anything. It’s been running there fat dumb and happy for several months. Why would the behavior of the HTML interface suddenly change?
Yesterday, it wouldn’t execute actions, either scheduled or in response to a programmed button press from my RemoteLinc.
