Hey guys, Allegro 610 Expert, Windows XP Pro. Well, my design has become "possessed"! No matter what I do, the Status shows DRC errors as "Out Of Date" with 0 errors: - I ran Tools -> Database Check (both checked), passed squeaky clean. - I ran Tools -> Update DRC, resulting in "No DRC errors detected". - I ran "Update DRC" from Drawing Options window, Status tab, also resulting in "No DRC errors detected". - I got out of Allegro, got back in, then I repeated the above. Anyone ever see this one? In all my years using this tool, I've never seen the DRC errors stay "Out Of Date" after updating. Thanks for any help! Gary Gary E.
