Comment:
I think I've fixed this bug. Please test GRASS 6.5 svn R39213.
It does not crash and display and zooming work in both constrained and
unconstrained ("explore") modes. If you try repeatedly to zoom out beyond
the maximum latlon (i.e., beyond 90N or 90S), the behavior is
unpredictable. But it gives a clean error when it can no longer handle
zoom out beyond what is permissible.
Coordinates all seem to be accurate (i.e., the pointer seems to return the
correct coordinate), and coordinates beyond 180E become West, and vice
versa.
Please test. If it is satisfactory, it can be backported to 6.4.
Note that it seems that the wxpython display does not seem to suffer from
the latlon zooming bug, but functions pretty much as the fixed TclTk GUI
does now. That is, it is unpredictable if you try to zoom beyond the
maximum latlon, but otherwise works fine.
