I've recently started getting a "You're out of storage. To copy this content you need more storage space." message when I try to save files from a browser (either Chrome or FF) directly to my Dropbox. I've got the free 2gig account and all indicators (both through Windows explorer and my account on Dropbox) - show that I'm only taking up 378.7 meg of storage. I just double-checked my backups and I have none (neither visible nor hidden/deleted).
I can still save the file 467k .pdf locally and then upload it to my Db through explorer without issue, so I can confirm that I truly do have enough room.
Any thoughts?
