It isn't that, since I haven't got any .3d files lying around in that
directory, and anyway in my case the program's working directory was the
one the svx file was in. Anyway, not getting the option to display dates
happens whether or not I'm processing from within Aven.

Another interesting point: although I've updated my cvs copy to get hold
of your fix to the other problem I mentioned, with it crashing on
loading a file with no date info if "colour by date" is switched on, I
can still make it crash as follows. If I process all.svx with cavern
1.0.37, load something else, turn on date colouring, and load all.3d all
is well - it notices there is no date info and loads it with no
colouring at all. However, if I process all.svx with cavern 1.1.6 and do
the same, it crashes on loading, with the same error at gfxcore.cc line
2193. This suggests to me that there is something very odd going on with
all.svx in particular. I can't work out why, since it handles
smk-system.svx fine, although it also dies on all-with-tracks.svx.

Incidentally, whenever I process anything from within Aven it throws up
a window saying "Survex 1.1.6 Copyright 1990-2005 Olly Betts", but
nothing else appears in that window. I presume it's supposed to print
the usual progress messages and final summary of length, depth etc to
the window, but (for me) nothing appears.

I'm using SuSE 9.2, GCC 3.3.4, and the Aven about window says:
