I have two different windows 8 machines that I use on a regular basis. Since I move back and forth between them frequently, I often edit the same office file on both systems. I recently began using SkyDrive and all relevant files are located in my skydrive folder. SkyDrive is set to run on startup and use Office to speed synchronization.

Several times now, I have edited a file extensively on one machine. When I go to open the file on the other, I see dozens of files such as

~$filename(1)

~$filename(2)

...

~$filename(72)

I also have a "filename" file, but it is out-of-date and does not contain my edits.

If I visit the skydrive website, I only see the single, correct, updated file.

What do I need to do to fix this frankly terrible behavior?

Office 365

Windows 8 Professional x64 (running on a Surface Pro and a custom desktop)

Skydrive

All windows updates are installed
