it's normal that in your demo page about Dropfiles, I see PDF (and DOCX too, and others) preview like text files (as in attached image)?
I'm very interested in Dropfiles; but with "The preview is displaying well currently by the way" what do yuo mean? Perhaps the version I will download will not have the problem? Because in the demo the problem still remains (text file preview for docx, xlsx and pdf). I'm confident that the problem in my web site will be resolved; could you reassure me?
