Although we don't use DWB tbl, I've fixed this problem in the early-ditroff version we do use, the problem might be the same. Check out the code that frees sep. I guess you'll find that it does just that. It should of course free --sep. This is an EXTREMELY DIRTY FIX. Use your imagination to make it tidier. Ian Utting iau@ukc.uucp
