Using the the other day, I found that when zoomed in a fair bit (the scale (which is excellent by the way) showed about 30nm), the moving map didn't work. The aeroplane stayed stagnant and the map didn't move under the aeroplane. Zoom it out a bit bigger and it was OK.
For a future update, the track up option is awesome and I've used it quite a bit. It would be nicer if we could go 'track up' with the aircraft position toward the bottom of the screen rather than in the middle? I'm not so fussed about what is behind me!
If I've got that wrong though in terms of use, let me know.
