Hi Rick,

Some versions of the "Helvetica Fractions" font can cause troubles
with Mac OS X. Maybe this has somehow been brought to the fore for
you. If you have it, try to remove the Helvetica Fractions font (e.g.,
move it out of all font folders -- don't merely "disable" it in
Suitcase). Apple has some tips:
