Q: Compiled help file opens but does not display page

Win XP Pro SP 3

The .chm file opens & displays table of content, but all pages show error "cannot display this page".

There is NO security warning on opening.

There is NO "unblock" option in properties.

Other .chm files run OK, some only AFTER unblocking, some after OK to security warning.


Is there a registry fix? The only related issue on MS I have found suggests the two above fixes, and fixes for Server 2003. My problem is with a local file.


Thanks for any suggestions.
