Hi, I try to install PPchTeX without any result. I get the message : systems : begin file essai2 at line 5 Randomizer initialized to 1239237573. figures : figure essai2-mpgraph can not be found figures : figure essai2-mpgraph can not be found layout : calculating backgrounds [1.1{psfonts.map}] systems : end file essai2 at line 23 ) What's wrong with metapost? In the archive I found a message from Denis B. Roegel about the same problem but I can't find his solution... Hervé
