Maybe you have a Gtk+ theme installed.
You can't defeat a theme engine when it decides to draw
things its way. If you really really need to draw them your
way, you have to draw them yourself. Drawing progress bars
is not hard, look at gtkprogressbar.c source. (You may want
to draw all progress bars in your app to keep it visually
consistent at least with itself.)
