Initially, dropbox got stuck downloading one file (contents.js). Everything else from other Dropbox apps would sync fine, but not that file.
Then at some point dropbox got stuck downloading 2 files, except it won't say what they are, but one of them is still contents.js.
Just now I decided to see if I could clean it up by deleting contents.js off the dropbox site, and then resyncing the iphone and the Mac, and now Dropbox is stuck updating 3 files.
The problem has been going on for several months. I've tried stopping and starting Dropbox, I've rebooted plenty of times. I'm at a loss. Next steps?
