I have some problem with gv or gs in my core 1. If I print a page in mozilla, only the title line is printed, but if I print it into a ps file and try to open it with gv, or ggv, an error message of "invalid ps format" would appear. Also I can get the same error to open a ps file generated in other machine with Redhat 9 by "mozilla -- print to file". But in the core 1 I can open and print the ps file generated by "latex + dvips". My system: gv-3.5.8-23, ghostscript-7.07-11, mozilla-1.4.1-18. Thank you very much! Gang
