I've been here too Peter. Protel can be a messy blighter, leaves little
bits of segments all over the place. I am not a power user so there might
be better ways but I have found that I needed to remove every last trace of
old copper before the DRC and autorouter would behave. I have used various
strategies to pick out the unwanted bits. Basically it has been a manual
"search and destroy" mission for me.

Thanks to Steve & Brian who replied to my question; I have checked the
points they raised, and still no luck.
However, I noticed today that when I start the Autorouter, there is
quite a bit of copper already on the PCB, from previous sessions. Maybe
I'm doing something completely wrong, but my process is:
1/ Place components as ideally as possible
2/ Autoroute. DRC reports clearance errors and short circuits
3/ Tools, "Unroute All" (but about 15 tracks remain)
4/ Adjust component placement
5/ Autoroute. DRC reports clearance errors and short circuits again
It looks as though the Autorouter is unable to work around all the
existing copper - is there something else to do to 'purge' the board of
copper, in addition to 'Unroute All'
Thanks, Peter Moreton
