1. Windows 7 Machine with the desktop Skydrive App - All up to date

2. Windows Surface pro 2- Latest version of Windows 8.1

3. Windows 8 Pro Desktop - Latest version of Windows 8.1

Here is my problem:

I open a PDF in the desktop version of Adobe reader (Latest version on all devices). I am able to highlight on on the Windows 7 Machine in Adobe Reader, click save, it then asks to "save as" so I replace the old document. Great, everything syncs I can then pull it up on the two Windows 8 Devices.

Now, I on either Windows 8 devices I do the same process, open the .PDF file in desktop view, add notes and highlights and click save, then it asks to replace the existing version, great again, it saves. However, it will not update on Skydrive at that point. I have to go into Skydrive on one of the other devies, delete the older version on that other computer for the new version to be able to sync. If I do no delete this file then no other folder or file on Skydrive will sync until I delete this older version.

I am at a loss! I have tried it with so many PDF's and the same result! I am about to go back to Drop Box! This is the most simple task and yet it fails at doing this. It is only doing it when saving .PDF in the desktop application, it doesn't do this with any other file type or in Adobe Touch.

Does anyone have any idea's?
