Thanks Steve and Brad... I will try very hard to avoid having that condition arise in the future... however, Protel needs to add that check to the DRC program to deal with the potential error condition so we don't make bad boards. I have to say this is the first time I have run across something the DRC didn't catch or flag, it has been a pretty reliable program but this is defiantly a bug that needs looking into and resolution.
