Greetings, I have just installed mathml-fonts[1] on FC5 and now firefox hangs on an XHTML document I have. I have tried both with Firefox 1.5.0.1 and 1.5.0.4 from Core. It even gives that warning about MathML fonts missing. Before installing mathml- fonts, Firefox would just render the document badly. > strace firefox does not make any progress when trying to opening the file. I have tried to search the web[2], but nothing useful came up. Do you have any ideas about how to approach this problem? Regards, Peter Eriksen [1] Using right-click -> Open with "Install software" on the mathml-fonts RPM from Extras.
