>I us "help file invoking". I get a list of 13 messages back, but none of the message titles links to a message. Also, come of the columns in the file are filled with "###.#####" kind of stuff. BTW - I was just trying to find out why my .chm help file would display on some machines but might not others. Puzzling. TIA.

See if this would help CHM help file shows error messages instead of help pages FAQ #28607
