;D The expand now works beautifully! Thanks for the fix!
...however...

the View Routes screen does not keep the default settings, e.g. if I want to view routes only below a LF of 75%, after editing a route, the page shows the standard setting (i.e. show all routes by hub).
One more thing, this has been reported under other threads: the View Routes tab has become really slow since the uptade (Note: I understand the game is free --- it is indeed a great game, just wish the performance would be par with the pre-update state...)
