10% of what? The final resulting arrival height?
Yes. I ran the following experiment: start XCSoar in Sim, increase height
above
ground, select a GoTo target, read values of the final glide bar and the
displayed arrival height next to the selected ground target (should be
identical). Now add a headwind comming exactly from the direction of the
selected GoTo target. Again read the two values (are less, than w/o
wind) - now
the values are considerably different, suggesting, that the influence of wind
on
the displayed arrival height and the final glide bar is different. In earlier
version, at least in 5.2.2., both values were still identical, as I would have
expected.
This is not to do with rounding errors, it's due to an angular approximation.

Because LEFT/RIGHT now page through the display modes.
Ok I understand
to 5) yes in version 6.010 on my IPAQ3870 gestures could be enabled / disabled,
not however in version 6.10.
Correct. We try to reduce the number of configuration options as there are so
many, it is daunting for many new users.
Makes sense
to 6) in version 6.010 one could lock the system settings during flight by
enabling the safety lock feature, preventing an accidental change of key
parameters during flight
This feature was removed.
to 7) circling wind calculation definetly seem to be buggy. In previous
versions
i.e. 6.010 the values were never so far off in comparison the my onboard LX7000.

Please report with an igc log file to www.xcsoar.org/trac
Wind calculation has not changed since 6.0.10.
Gladly, have to wait until next weekend though. I will provide the XCSoar log,
the LX7000 log and the Flarm IGC log. I will also flight to test with previous
versions (6.0.9, 5.2.2.), which were the ones I had previously used.
