I have an idea of what might be wrong here, which is consistent
with this experiment working on Ubuntu but not on Windows. A gretl
graph is saved in the form of a text file containing the gnuplot
commands, inside the current (hidden) session directory. The thing
is that the filename is (I think, I'll have to check) the same as
the name chosen for the graph.
So if Henrique saved a graph under a name which contained UTF-8
accented characters (inside gretl, everything is in UTF-8), these
would turn into weird stuff on the Windows file system (Windows
never uses UTF-8), and gretl would then be unable to find the file
again.
If that's the correct diagnosis, I guess the fix is either (a)
insist that graph names are ASCII (maybe unpopular) or else (b)
don't use the graph name to name the associated file of gnuplot
commands. This is of course a bother because it means we have to
find some other way of keeping straight which file goes with which
graph. Now if Windows "got with the program" and used UTF-8 we'd
be fine...
