Hi there, I have a problem with lyx-1.3.6. The mathematical signs like \cup \cap \int are not displayed. Instead of it I get empty square. I have no idea what I should look for. Please help.
Thanks in advance for any suggestions. Best regards. Greg PS. I'm using X11-org-6.9.0 -- ______________Pozdrówka___________ / ___ ___ ___ ___ ___ / _ /__/ ___/ /_ /__ / /_ /_/ /__/ / | /__ /__ ___/ / /__ / |
