Agreed, Frank - it was a real problem for me, but now the grid is rock solid. As with you, the "focus" on the selected aircraft on the map does disappear.It would be nice if that could be fixed, but I can live with it.
But having routes in the routes table, with recent dates, but not showing up on the grid or map, is very frustrating. My feeling is that the situation is better than it was before (more routes are showing), but it certainly could be better.
I think the ball's in Andre's court on that one.
