Hello Martin, thanks for your questions. I answer below, to your and to the Dan questions:
1) Yes. What I report happened in Italy. On Saturday coming from Montagnana to Padova (my home), on Sunday coming from Ferrara-Rovigo to Padova. 2) The value on the infobox and the track arrow was wrong (30 degree to left of final waypoint) 3) Yes, the position fo the fona destination (waypoint Padova) were different from the track line 4) Also my group said me if I mistake the waypoint. But I used the same file of waypoint (named LX20-2015.dat), before with IPAQ 3950 with Flarm and then with Android device, the same on Saturday and on Sunday. And the same file allways took me home (until 300 km) 5) the wind were set for "both" automatic option, circle and zig-zig. 6) I used allways the same profile, ls1.prf (I fly with LS1-f), before with Ipaq and Flarm and then with different XCsoar verson on Android device 7) I used the GPS inside the Android device, internally connected to XCSoar. So I have only one device. Thanks to Dan for McReady setting information, I will think about, but I don't think is relevant with the problem reported. I understand that you have many questions for me, and I respond gladly. But please, consider that I keep XCSoar training sessions to my group. I sponsor XCSoar from the 4.2 version in 2005. You can ask to Scott Penrose and John Wharington, and more recent to Max Kellerman. In 2006 I gave a very little contribute with language translation in Italian. So please, I can mistake, but I intend to give a contribute to solve the problem if exist, not to create it. Please, feel you free to send me other questions, I will respond gladly.

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.
