问题 I have been using iTextSharp to generate PDF documents for over a year. Unfortunately, with the release of Adobe Reader X, my PDFs now cause a "Do you want to Save?" dialog to appear when closing the PDF document.

问题 I am using iTextSharp to place an image and some text on every page of a PDF. This works perfectly for some PDF's but not for others. Strangely enough it does not work for instance on a PDF I created with Word 2010's 'Save as pdf' function. I use GetOverContent, which should everything on top.
