Upon further investigation, it seems that wmnetload doesn't cycle
between all interfaces when the right mouse button is clicked on the
dock app.

I'm still seeing such problems, but now I've run it through valgrind and
I see many messages of the type: "conditional jump or move based on
unitialized value, blah, blah".
Also, I found an unitialized variable being used. The source for that
was a typo. In file wmnetload.c::approxpixel, the following snippet of
code is wrong:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
diffr = (red - colorcells[i].red) >> 8;
diffg = (green - colorcells[i].green) >> 8;
diffr = (blue - colorcells[i].blue) >> 8;
approx = diffr * diffr + diffg * diffg + diffb * diffb;
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Obviously, the variable corresponding to the blue color is diffb, not
diffr. This fixes one problem.
There are also other initialization problems regarding wrong number of
initializers for structures.
Also, some signed vs. unsigned comparisons are made in the c files.

Lorenzo, are you listening? Please, reply. I fear that some drastic
measures would be necessary if we *continue* to have no feedback from
you.
Thanks, Rogério Brito.
