There is nothing wrong with the document. It is just the viewing pane. The document prints just fine.

When I open an Invoice in 8.x the magnification is less than 40% caused by squeezing the right edge to some point(I don't know what that is). I close the document, no save, and open the same document on 6.x and it opens more than 95%.

Here is my normal invoice processing procedure: I open the Invoice.pdf, open the page frame, open my additional pages document (usually a signed PO), drag the additional pages to the original invoice document, and save the original document ready for SEND to the customer. For 8.x, after opening the document, yes I can drag the window wider but then my customer may have a problem when they open the document if I save with the original "Resize" flag set.

I have searched through all the Acrobat options and can find no other option or setting that may be set incorrectly in V8.x. I will admit that am NO expert in Acrobat just a user. Again, my assumption or best guess is that Acrobat fixed something 8.x that was not working correctly in 6.x. The check box appears to be the same in both.

I am not a developer so I don't know the requirements to create a compatible pdf file. I am just trying to protect my customers from frustration in opening the file and having it small and unreadable. I am assuming they will get a small window if I don't touch the pdf file, as in AR statements (I don't update these).
