/usr/local/texlive/2008/texmf-dist/doc/latex/isodoc/isodoc.cls Thanks for the report. It is fixed for TeX Live 2009. 2008 will not be updated. Best, Karl P.S. to all: I will be offline the next couple days. Back Sunday. Some of you may have noticed the big amsfonts update on CTAN. I'll deal with this when I get back.
