I have a user that receives files from a source that is still using WordPefect. After an upgrade to 8.5 these attachments (with a WPD extension) can no longer be viewed. Clicking on View generates a “The viewer display window could not be initalized” I have tested this on other workstations and the problem occurs if they are running 8.5. (I would rather ignore the problem and have the sender upgrade to Symphony, but this is unlikely to happen.)
