I haven't the slightest idea... I'm running AltaVist Tunnel 97. A five year old binary with no source. I guess I should be glad it lasted this long. It worked perfectly up till 4.3, had a slight routing problem in 4.4 and is DOA under 4.5 I guess it is time to roll back to 4.4. Perhaps a complete trace under 4.4 will give me a clue as to what it is trying to do. But I'll still need a way to disable that automagic route addition. thanks, davep Julian> On Fri, 1 Feb 2002, David A.
