I have a Win7 PC that seems to be displaying all PDF pages that are opened in PDFElement as blank white pages. If you go to a function that displays the thumbnails of all the pages you can see the content, but as soon as you go back to normal reading mode the document is a bunch of white pages. You can make edits like inserting another PDF document and save the PDF and then open that document in another PDF reader like Adobe Acrobat and everything looks great including the inserted document. The seems to happen for any PDF document you open with PDFElement. The machine has PDFElement 220.127.116.1123 installed. Are there any known bugs around this issues or fixes I can perform to solve this issue?
