In the meantime, let's try to make it stop breaking for you. fltk's src/x11/Font_xlfd.cxx asks for "fixed" and "variable" under certain conditions. In my case, they seem to be (looking in /usr/lib/X11/fonts/misc/fonts.alias) fixed -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1 variable -*-helvetica-bold-r-normal-*-*-120-*-*-*-*-iso8859-1 And then in my /usr/lib/X11/fonts/misc/fonts.dir, there's 6x13-ISO8859-1.pcf.gz -misc-fixed-medium-r-semicondensed--13-120-75-75-c-60-iso8859-1 and then /usr/lib/X11/fonts/100dpi/fonts.dir has helvB12-ISO8859-1.pcf.gz -adobe-helvetica-bold-r-normal--17-120-100-100-p-92-iso8859-1 and /usr/lib/X11/fonts/75dpi/fonts.dir has helvB12-ISO8859-1.pcf.gz -adobe-helvetica-bold-r-normal--12-120-75-75-p-70-iso8859-1 Do you have whatever font 'variable' is set to in your fonts.alias?

Unexplained Dillo Segfault

Every time I visit a web page, I get an unexplained segfault (viewing with strace). This has been occurring for 1-3 months now. I've recently realized a GCC bug with Mozilla based browsers here: http://bugs.gentoo.org/show_bug.cgi?id=270120 I think on one segfault with Dillo, I did get a "bad var font" error, but later lost the url -- so I can only try to recall the exact error. I doubt this is font related as I have several fonts installed.

Hi all. Are you able to control vertical and horizontal scroll bars in the below example? <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> </head> <body> <textarea cols=10 rows=10> Test message 1 - message 1.
