Problem 1: Is the linked CHM om your own machine or on a server? If it's on a server, then you may have hit the 'security patch' that MS brought in about 12 months ago. Check the MS Knowledge Base for 896358.

Hi, I've inherited a Help system and I know I didn't have all the files when I started but now I have these problems. Scenario Individual software modules Individual chms in large context-sensitive help system Users may have any or all software (and so Help) modules installed TOC displays as if all are available but really you only have access to whatever is installed Done by making a master chm then taking master.hhc and including it as a baggage file in all modules Problems Only one module does not work . It's there in the master TOC but clicking throws the error "The page cannot be displayed". However, the chm works on its own. Can end up with multiple instances open. Not displaying in one window. I could live with problem 2 but problem 1 is unacceptable. I would appreciate some expert guidance. This is due by COB today (product master tomorrow) and I'm frantic. I've been debugging it for a month and I can't finish it off. Thank you. --------------------------------- Regards Marcia Bascombe MYOB Australia Pty Ltd marcia.bascombe@xxxxxxxx
