Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

Send a bug to Microsoft then - it's obviously because they fucked up something (again).

If you unblock the file first (by going to the properties), it works fine.
I think the fix is to sign the files, but thats not an option.

Description:
------------
I work with PHP Designer 2005. It has an integrated "Help"-Plugin, which
uses the chm-files of the php.net-Documentation. After today's update,
via WinXP Auto Update, this Help-Plugin doesn't work anymore.
So I opened the chm-File (DE and EN) with the Win-Help.
- On the left side there was the complete tree
- On the right side, where the contents should be shown, the HTML-Error
Page appears which says that the page could not be shown. That happens
for every point of the tree.
It might be, that the WinXP-Update 896358 is the reason for this
problem.

Solution:
---------
Thanks for your answer nlopess. It works.

It's still bogus.
