I've been having an issue with the map, but I'm not sure if it's by design, or a bug.
I like to have the fullscreen map open to monitor an airport's activity. It seems that when the mouse is hovering over the active map, no flight data on the aircraft is displayed. The aircraft icons are there, but not the accompanying data. However, if I hover the mouse over the ads on the side of the screen, or outside of the active window, the flight information comes back. The problem with this is that each time the ads switch to the opposite side of the screen, I have to move the mouse over there to see the flight data again.
I really would just like to leave the map up, and not have to touch it while viewing the flight data.
So, is this an intentional design feature? The map itself works great, I just wish the data would stay displayed.
As a side note, it would also be nice to have the IFR airway route maps as a background option, as it seems to be more useful than the standard sectional chart.
This is by design. It's a compromise between having lots of data shown at once and wanting to point at just a single flight. You will have to leave your mouse outside of the map area for it to continue cycling through labels as you'd like. I suggest clicking the reload button and then leaving the mouse there at the top. Let me know if this doesn't work, and if so, what browser and OS you're using.
