Erwann & others, ea> What is the behaviour, apart from the log file? This is the last complaint on the screen. "Specify a program on the command line or make sure that /usr/X11R6/bin is in your path." Should this path item be system wide? Where should it be set? There is no path in my .bashrc. Where is a user specific path set? Thanks, Peter E. Peter Lyall Easthope http://carnot.pathology.ubc.ca/
