[OS X TeX] yhmath package

[Leah Berman]

Hi--

I've been having a couple of weird pdf rendering issues, and I was  
hoping someone might have some good ideas.

I'm trying to use the yhmath package to put an arc sign above several  
letters (as in, arc ABC), using the command \wideparen. For some  
reason, the curvy bit that is supposed to show up over the letters  
doesn't. I can see it using a PC, but not on the pdf from TeXShop (It  
doesn't show up using either TeXShop, Preview, or Acrobat.) It doesn't  
seem to matter if I am compiling using TeX+ghostscript or pdftex.

Also, I have some .eps graphics (geometric diagrams) that I converted  
to .pdf using TeXShop and then included in a .tex file. Mysteriously,  
although the graphic looks great in TeXShop, when I print it, some of  
the letters are missing, and they're also missing if I clip it from  
TeXShop (say, to stick it into a keynote presenation using expose).

Any ideas would be much appreciated!

I am using OS X 10.3, TeXShop 1.34, and the TeX I get from the  
i-Installer, but I haven't updated that in a while.

Thanks,

Leah
