Thanks to Felix Homann hint to look at... http://support.wolfram.com/mathematica/systems/linux/interface/fonterrors.html
...I solved the error message from mathematica. The origin of the problem was that I had over 3522 fonts and the setting in... /usr/local/mathematica/SystemFiles/FrontEnd/TextResources/X/Specific.tr ...for @@resource maxForXListFonts was set to 2000. Once I bumped that up to 4000 the problems disappeared. Jack -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
