• Hi,

    I have a problem viewing some PDFs when using UNC paths. My problem is this:

    I have an application using WPViewPDFPlus3 running on a server. I use this application (among other things) to view and manage PDFs. When trying to view certain PDFs, the viewer shows only blank pages. This seems to happen only when my application is run from a UNC-path, when I copy the application to my local harddrive in runs great, and when i map the directory on the server to a drive letter it runs great. I've also tried going back in time, and when using WPViewPDF3Plus.dll 3.24.4.872 (2015-01-05) or 3.12.6.649 (2014-04-28) it doesn't work, but with 3.9.8.417 (2013-05-17) it works.

    Hope you can help me :)

    I'm on Win 7 Pro x64, if that matters.

    WPViewPDF has this 2 methods:

    function LoadFromFileAsCopy(const filename: string): Boolean;
    function AppendFromFileAsCopy(const filename: string): Boolean;

    Both will completely buffer the file so it should not put so much traffic on the network.
