Compiled help (*.chm) problems after last updates

After last set of updates (7 updates) I encounter problems with accessing
*.chm files which are not stored locally on my hard drive (they are on net
drive).

The *.chm help file opens without any problems, Table of Contents, Index and
Search work fine but in the right pane no HTML is displayed and "Action
cancelled... " page is displayed instead so the help is useless at all.

It looks like some security issue, but I cannot think of any sollution...

Hi,

This is caused by the security update KB896358 (MS05-026: A
vulnerability in HTML Help could allow remote code execution)


Importing the registry file below will solve the problem as long
as your network drive is defined as "Local intranet zone" (it should
be).

Put the following in a .reg file and import it by double clicking on
the file:

--------------------8<----------------------
REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\HTMLHelp\1.x \ItssRestrictions]
"MaxAllowedZone"=dword:00000002

--------------------8<----------------------

The setting above will open up for Local Machine zone, Local intranet
zone, and Trusted sites zone.

More about this registry setting here:
