The front end is having trouble with the default fonts (dt foundry) of CDE, and this leads to a seg fault. You can fix the problem by overriding the font selection with the following X resource: XMathematica*fontList: <some font here> where the font name follows the X logical font description convention: http://www.it.umd.edu/unix.help/Utilities/X-windows/XFont_Fields.html The resource line should be added to your .Xdefaults file in your home directory. If this file doesn't exist, create a new file by this name with the above line it it. I use Helvetica-Medim 12 pt in my work, so the resource setting I use is: XMathematica*fontList: -adobe-helvetica-medium-r-normal--*-120-*-*-*-*-*-* However, any font available on your X server will suffice. You can get a list of the fonts by issuing the command: xlsfonts | more in a shell on your Digital Unix machine. -- P.J.
