tarbat, just a thought - if you select "Get flights from Network" and leave your PC for a bit, does it come back to normal after a short while?
I saw this with V1.3 when I started RB - After the initial connect box comes up with username/password and the RB interface runs, RB then seemed to "freeze" whilst it connected to the network. So although live flights came up almost straight away, it would take 5-10 seconds for the network stuff to appear, then a few more seconds before the interface was "clickable" again.
Next time you try this, select network data then just leave RB for a little while to see if it sorts itself out.
