I have lots of PDF documents on my site that i make available to casual visitors - you can see them at http://www.odquiz.org.uk/quizzes.aspx
They work perfectly well when used with PC's but I have discovered recently that I cannot open the documents using my Android tablet or phone. If I click on one of the files it opens a new browser window, but the file never opened and is not downloaded. I can save the file by holding down the link and then choosing "save link" from the popup menu.
Is there anything I can do to cure this? If I put the file in my web storage and set up a link to the file, either as a hyperlink or using the List/Links feature, it works perfectly, but I would prefer to used the shared files feature to allow me to use folders etc.
