Aircraft track hover/select is buggy

[electricshaman]

1. If you click the "Show All Tracks" button on the map and then mouse over an aircraft icon, the track disappears.
2. New aircraft that appear on the map after "Show All Tracks" is clicked do not show their track.
3. Sometimes when you mouseover an aircraft, the track remains visible on mouseout even though the aircraft icon has not been clicked. Seems to happen only when the aircraft icon has been previously selected and another aircraft was clicked.
