Nav details in-sim map (V)

[simtech]

I've done something that I don't quite know how to correct. I always used the in-sim map, V key. I would click on a nav-aid/airport and the details (freqs. hdgs, etc) would pop up on the right. It no longer does so. Any ideas as to how I might get that function to return? TIA, Clear skies to all. Terry
