I am running windows 8.1 and since the upgrade I am having quite a frustrating issue in regards to my files syncing.

I don't sync my entire Sky Drive just selected folders and what I find is that when I change the availability to 'offline' everything eventually downloads ok and they are all synced up offline. After an arbitrary period of time I find that they mysteriously change back to online-only for no apparent reason requiring me to re-download everything again.

Any help to stop this happening would be appreciated.

Thanks :)
