When I open a PDF file in Acrobat X often the page(s) need to be rotated. This is easy enough to do and easy enough to save the document. The bug is that the saved document doesn't remember the rotated view. This worked in previous versions of Acrobat why is it not working in version 10??
I discovered that there is a difference between page view rotation and page rotation. If I actually rotate the page then this problem goes away and I can save the file with it's new orientation in tact.
