I have a Drupal 6 intranet site. We have numerous hyperlinks to files stored on our file server. These links are "file" links - e.g. "file://server/shared/myfile.doc"
They had been working fine for months and then suddenly they stopped working. When the user clicks on the URL, nothing happens. Pointing at the URL makes the cursor switch to the pointer finger - indicating it's clickable - and the path appears in the status bar, but nothing happens when you click on it.
This behavior occurs in IE, Firefox, and Chrome.
No updates have been made to Drupal.
If I do a View Source on the page, copy the HTML to a blank HTML file, save it, and then open that file, the links work fine! If I save the original page directly, it is saved as an mht file and then I open that, the links do not work.
I am at a loss of where to look to identify the source of this problem.
Any ideas would be MUCH appreciated.
