I have a project that uses Smarty (PHP template engine). I need to continue with this project, so I downloaded Smarty help file in CHM format to check some configuration options. To my surprise it showed a error message: This program cannot display this page". I am pretty sure that file is ok.
I went to the Internet, searching. after 5 minutes I found it. Microsoft tightened security so much that it affected CHM files. If CHM file is downloaded as is (not archived or as a part of another package), no one will be able to open it because Internet Explorer thinks that untrusted HTML tries to open in Local zone. Moving file does not help, Internet Explorer watches all moves. Damn. What do I do???
The answer is easy: zip it, move to another directory, unzip, open and read. That's it. Stupid but nothing else helps.
For details you can read this excellent article.
