Hi,
I have noticed something strange with files that have been customized with aspose pdf library.
After opening a file (for our example, watermark added by aspose), and changing zoom or hovering over the inner attachment in the pdf, once you try to close the file Adobe reader alert pop
"Do you want to save changes to 'example.pdf'' before closing?
This is reproducing in Adobe reader only and with files that aspose customized...
In foxit reader it doesn't happen....
Attaching the example.pdf file
Thanks
