it's the \scalebox{0.5}. The annotations are in a separate PDF area and
are unfortunately not scaled with the rest (current pdftex can't provide
this, technically), so the annotations move away from the section
numbers 1 and 2. To see this, try to set the \scalebox{} parameter to
values between 0.5 and 1...

that't normal. The red boxes are only for clicking, screen navigation.

try to avoid this picture scaling (e. g. by scaling the font inside the
picture). But anyway better for presentations use a LaTeX presentation
package like "beamer". Gives you many goodies (navigation, font scaling,
sequential page build-up, nice backgrounds and frames...).
