Hello,
we have a problem with our CHM files in Windows 8 / 2012 environment.
If we try to open a PDF file with a link inside CHM, it don't open nothing, just shows a little black "X" in the CHM window.
The link are made like this: <a href="file://PATH-TO-THE-FILE">Link name</a>
Please note that we install Adobe Reader, and normally the PDF are showed succesfully inside the browser.
In other operating systems the problem doesn't happens.
Have you an idea of the issue's cause?
Thank you very much
