i don't know whether this is the right place to ask this question (maybe
the flaw is in kml or in googleearth) but it is the only place i found
to hopefully provide some answers.
version: gpsbabel 1.3.5
os: linux (32 and 64 bit), windows xp
source: sony cs1 (nmea clear text log)
i tried to convert my tracking and skating gps data from nmea to kml and
found some weird behaviour in googleearth: when using trackdata=0 during
the conversion hitting the 'play' button to view the trackpoints move
works without problems. when using trackdata=1 only some trackpoints
flash for an inch of a second.
but: after opening any (!) single track that was converted using
trackdata=0 all tracks with trackdata=1 open with the trackpoints fully
visible during play.
i tried in all my operating systems with different versions of
googleearth and the behaviour was the same.
is there any way to include trackdata and have the trackpoints visible
when 'play'ing the track?
thanks for any advice in advance,

I've never seen what you're describing. GPS tracks with trackdata=1 can
result in large KML as each trackpoing gets a clickable balloon filled with
a fairly chatty bunch of test. There's definitely more file I/O and Earth
has to work harder which, if you're dealing with thousands of points, might
cause some flickering.
The newfangled 5Hz GPS loggers can really exaggerate this effect, too.
Stiill, that really doesn't describe the "sticky" behaviour you're seeing
where the previous load of one type changes the behavior of another.

I've seen that requested in the Google Groups for Earth. Earth doesn't
automatically expanding/collapsing the placemark balloons during play.
