Just out of curiosity and to narrow down on the magnetic track issue: All you are reporting happened in Italy, right? Or are we talking different locations or even hemispheres? I can' t see trying different versions at random leading anywhere.
What exactly was wrong? Value in info box, or track line on map? If one of the above, was the track line different from the value in the info box? Was the own position at the time displayed accurately? Was the same waypoint file used in all cases? Was it accurate? Were the same prefs used? Was the wind set manually or auto in all cases? Before trying versions, I'd compare settings and data used, and make sure they all match or are in fact fully supported by the actual version used, to exclude possible sources of error.
