  1. None worked. Thanks for the info though, I can see it has worked for others so that’s still a good thing.

  2. Had spent hours changing settings and anti virus settings to get hyperlinks to work. This was important to me because I wanted to use them to link some documents to audio files.
    Changed the default browser as you sggested everything now O.K. Sick of Microsoft and ie problems so won’t be changing back in the forseeable future. Many thanks for your help.

    4.Change the value from “ChromeHTML” to “htmlfile” (or from FireFoxHTML to htmlfile)
    Repeat these steps for htm and .shtml keys if they exist. You may also want to check the xhtml and xhtm keys.

  10. Uninstalled Chrome to start the problem. None of the fixes worked. Reinstalled Firefox and it fixed itself.
