I'm running AutoCAD 2006 on Win XP. When I try to run the TABLESTYLE command (toolbar or command line) AutoCAD does nothing; it simply returns to the command prompt, with no error message or anything. I thought it might have something to do with the DEMANDLOAD variable, but it is definitely set to load ARX upon invoking a command (DEMANDLOAD=3). I can't think what else it could be other than a corrupted file somewhere. Anyone out there have experience with this sort of thing? Thanks, in advance.
