I can view a completed PDF file in "view pane" however when I open the saved file, it is blank.
What is your operating system?
What is your Adobe Reader version?
WIndows 7, Adobe 10
Try if updating to the latest version 10.1.3 still does the same.
If it does, please tell me your display adapter, device driver version & date; see http://forums.adobe.com/thread/945765
