hello everyone,

I finally managed to diagnose and sole a problem I've been having with the eldos help file for a loooooong time and, since I posted my enquiries in the old newsgroup, I thought I might put the solution here for future reference.

Here is the deal: when you download a file from the web using Internet explorer on XP SP2 or 2003 server, the browser will mark it as "web" content (it uses an alternate data stream for that).

Now, there has been several attacks against windows using compiled HTML (*.CHM) files as vector. So in SP2, Microsoft decided to try to protect the users by disabling the execution of CHM files over the network and safeguarding against local use.

As it turns out, you can't properly open CHM file from a network drive if they have been downloaded from the web. Even locally, you have a security warning and you MUST check the "do not ask this question again" check box in the dialog before accepting to open them.

My solution was to copy the CHM files to my local machine and open them from here. After than, I had no more "Operation canceled" error message when trying to view the content of a specific topic.
