Apparently one must be careful entering filenames manually into the
filename field (as opposed to using the Browse button).
The current policy for manually specified filenames is not ideal;
an "unpathed" filename (e.g., "myfile.tif") would get written (or read
from) the current directory. This is not too great because Leveller
doesn't actually ever say what the current directory is; it just goes
with whatever the operating system is maintaining (which is probably the
directory Leveller is running from or the last folder accessed by a file
dialog).
I have one idea for a better policy, e.g., always use the same directory
that the Leveller document resides in. We'd probably also want to
enforce a "no other relative directories" rule; e.g.:
myfile.tif --> uses same folder as Leveller document
c:\myfile.tif --> explictly uses root folder of drive C
.\myfile.tif --> error
..\myfile.tif --> error, can't assume any parent of Lev document
The Browse button could also be made explicit, but this would be
annoying for those who want to specify a filename that differs by only a
few characters from the previously specified filename.
