First my PC decided to pack in and is away at the menders.
So, I installed AirNav RadarBox on the laptop. All seemed well, so I updated to 3.13 and now find that the airfields around me are in totally the wrong place. For example, Stansted appears in a SW direction to me when in fact it is well SE. Luton has similarly moved further west too.
I am running Vista if that helps. Any suggestions gratefully accepted.
