(now there, thanks)

they seem clear enough to me, but ok.
how about clear and next then?


actually I think we can live without a "next" button if:

unchecking "Save" should write to disk immediately, close the
track_$DATE_000.sav file, and free that memory. Upon re-checking
the Save box a new track_001.sav should begin.


other issues/ideas:
the Track/"Show" tickbox tooltip: unticking "show" doesn't /clear/ the
data it clears the display. suggest rewording the tooltip. (if my
understanding about what it does it correct.

GPX: (cc'd to the GPX wish in the SF tracker)

* the program should regularly (every few minutes?) save the GPX track
data to the disk and flush it out of memory. Currently it seems it is only
written to the disk on exit, which is a huge danger of losing the
afternoon's OSM effort if the computer suffers a power loss (high
probability on a mobile platform). Also reduces the memory load if the
program is left running for days at a time.

* It is slightly dangerous to the data to simply overwrite rather than
append the data to the GPX file. I have no good ideas for a solution, other
than to follow the historic track_$DATE_000.sav, 001.sav, 002.sav, etc
method or simply appending like track-ALL.sav does.

font size or lack of hover-time issue?
