I have a lisp routine that I downloaded from the Cadalyst Magazine website that I was using with AutoCAD 2002 and Windows 98 ("Al's Steel Mill", March 2002). It is quite complex, involving a dialog box and several support files. I recently recieved a new computer with Windows XP. I installed all my software and reloaded my lisp routines. All but this one work, and I really have no experience with this sort of thing. I tried to contact the original author, but my email went unanswered. Any ideas? I don't want to give up this particular tool because I have come to depend on it.
