Hi
Recently I'm struggling to get routes to work on the web interface. If I try to load a Cloud or saved route, although the list comes up, if I click on it, the route is not displayed. I can't seem to get it to start a new route (no dialog box comes up) or even select airfields with the mouse (Options on right click are "Create a new Waypoint" or "View in Google Maps".)

I restarted the PC, tested on another PC, un- and reinstalled Silverlight.

Running XP Pro SP3, Silverlight version 5.1.30514.0, Mozilla Firefox 38.0.1., also tested in IE Version 8.0.6001.18702. IE reports the following error on the page:
