On Mac OS X 10.5, math fonts used by LaTeX do some weird things. Here is the incompressible Navier-Stokes equation typeset with LaTeX. The fonts are often displayed incorrectly by Preview, but sometimes they are right. As I focus on and away from Preview the way the fonts are displayed changes.
which editor are you using?texshop?

@Ermanna76 I don't remember what I was using at the time, but mostly use MaxTeX with its pdflatex command now. This problem went away some time long ago, probably after switching TeX distributions, and now in Snow Leopard I've not had any problems at all.
