Just one ... where do the CHM files reside? If the ones that are not
opening reside on a network (and so are accessed via \\server\share or
a mapped, network drive) while the ones that are opening are on a
local drive, I suspect the problem is security "enhancements" from
Microsoft.

Basically, Microsoft updated the HTML Help control to not open CHMs or
other HTML Help files unless they reside on a local drive.

http://www.microsoft.com/technet/security/Bulletin/MS05-001.mspx
http://support.microsoft.com/kb/892675 contain more info.

There is also an issue with cross-frame working for which MS updated
the HTML Help control to prevent content opening in another frame:
http://support.microsoft.com/default.aspx?scid=kb;en-us;896905 has the
information.

If these are the problem, the MS articles give Registry hacks to work
around them.

HTH,
