Wierd? Anyway, on Windows 7, I've downloaded a CHM file on the desktop and unblocked it by
Property > Unblock.
I moved the CHM file to a folder on the desktop to organize the files, and when I opened the file, the content of the CHM reader couldn't open the pages in the CHM file. I've open the file property, but the unblocked button is gone. Well, I can simply download the file, though I find the problem interesting and I need to know how to troubleshoot it.
So, how can I unblock the said file?
Update Clarified location. I was referring to a folder in the desktop, not in network drive.
