even though I set onedrive for offline access, there are certain files -- usually the ones that I desperately need, because I am actively working on them -- that keep getting switched to online only. Because of this problem I switched back to dropbox, although it is kind of redundant on windows 8.1, where onedrive is baked in.

this just happens on my laptop.
it does not happen on my desktop.

this is actually a problem I had a few months ago, maybe microsoft has since solved this bug?
