I have installed the trial version of Boxcryptor V2 this evening (8/8/13) with a view to moving my business from BC Classic. I have a critical problem which means I can't make the move yet.
When using the latest Office365 version of MS Word to edit files in a BoxCryptor encrypted folder linked to a Dropbox account, I lose the ability to save the file after a while. It works fine to start with, but I eventually start to get an error saying that it can't save the file and that I should check that the filesystem isn't full or read-only. Once this happens, I'm stuck as I don't even seem to be able to save the file anywhere else either.
I realise that this may be an Office, Windows 8, Dropbox or BoxCryptor problem, but all I know is that I've never had the problem when using BC Classic.
I can see that other people are having similar problems with Office/Dropbox/BoxCryptor2 combinations, but I haven't found anyone who has got a fix for this yet. When there is some kind of resolution to this I will consider the move again.
