I've just noticed that the SkyDrive folder on my Surface RT appears to show all its contents as 'available offline' and all are busy downloading onto my device right now. I didn't ask for this, and I can't seem to stop it.

I right-clicked all the folders on my SkyDrive and selected 'make available online only', but to no effect; the syncing continues unabated. I tried doing the same thing via the SkyDrive app, selecting 'make online only' for each folder on my SkyDrive, but I get the same lack of response. Solutions please?
