Presently I have 3.0.1, 3.0.2, and 3.1.51 (current as of Saturday) all  
running, so I can try all three out.

The titles are all correct, but the "\in" in xlabel produces a  
"therefore symbol" similar to AMS's "\therefore" but with small  
circles replacing the dots, and is followed by "316". The remainder is  
correct.

I'm on Mac OSX 10.5.5, and am using the aquaterm. When I use x11  
instead all looks as it should.
