Sorry, I had meant my reply to go to the list.

OK. Given that advice I'll look at how I can make it smaller.

OK, so usage is the same.
I'm not sure how much help I could be.
I don't think my programming skills are too good for anything other than  
Fortran, and that really hasn't kept up with the latest standards.
I do regularly build and test  (every few days) a Fedora package for  
another FOSS application (Hugin), and sometimes bug hunt for that, but I'm  
not too skilled in the bug hunting.
Let me know if there is anything there that will help, and we can see  
where we go from there.

Now back to my fltk problem.
I have now figured out (I think) how to correctly get the figure handle  
for printing, but that now causes another problem. Using the code below  
the plot is rendered in the display, then another plot is rendered  
slightly offset. If I comment out the print command I get the correct  
plot. Have I misunderstood how the figure handle should be used?

fig = fig + 1;
fig1handle = fig;
figure (fig1handle);
h1 = gcf();
mesh(x,y,Zabs);
xlabel('x axis');
ylabel('y axis');

print(h1,'results/mesh.jpg', '-djpg');
