I really don't know where to direct this problem. I have a manuscript that I format with groff -e -ms that has an inline equation using the eqn "sqrt" operator. When I format the manuscript to postscript, and look at it (with gv) or print it on a postscript printer, the square- root radical comes out perfectly. However, when I use ps2pdf to "distill" the postscript to pdf, the equation is a complete mess: it starts OK, prints the √ ok, but then backspaces about an inch, and prints the rest semi-randomly on top of the first part. When I use Adobe or pstopdf, I get slightly different errors, but neither is correct. It appears to be an interaction between how groff generates the postscript code and how the pdf distillers interpret it. I am using OSX 10.4.10, groff 1.19.2_1, and ghostscript 8.54_0. For the moment, I've used a little algebra and rewritten the relevant section of my manuscript in such a way as to avoid the square root, but it would be really great if someone could take a look at this for future purposes.
