Windows Vista CHM Issue

• You may find that on occasion you can not view the content of CHM files (ex. AHS Behavior resource file) on Windows Vista. You can see the table of contents but the actual details are not displayed.
• This can occur if the file has come from another computer, and the OS now blocks these from running.
• You can click the Unblock button and it will allow the single file to be trusted:
  • Right-click>Properties>Unblock
