Your previous suggestion to run lyx -dbg font was enough for me to track the problem down myself. Thank you for your help. For whatever reason, my urw-symbol font only has digits in it! (when viewed by xfontsel) I have removed this font from my system and am using abisource symbol instead. This works fine. Thanks for your help. Not a LyX bug at all, just that my machine is configured strangely. One unrelated comment. New LyX automatically uses the babel package. I found that many of the packages I use are incompatible with babel. It took me a while to figure out that I can delete the \usepackage{babel} from the language panel, and just leave it blank. You might include a comment to this nature somewhere where people who are upgrading LyX will see it. Best Regards, Gregory Plett
