1) If I look at files in my SKYDrive folder they have a tick mark against them indicating I believe that they should be synched with the CLoud. However when I logon to the CLoud the file is an older version. This suggests that files from my Windows 8 PC are not being uploaded correctly. The only way I can get them to upload correctly is to stop / restart the SKyDrive desktop app. Is this a bug?

2) When I am working on a file and save it, how long should it take to get uploaded to the CLoud?

The files I work with are MS Office docs. I have linked my folders to the SKYDrive directory using the mklink command
