Dropbox is stuck syncing after an update, what can I do?

Also have problem here. This machine has been online uninterrupted on a 1GBit internet connectio, still, though, it says 65 files to sync, taking several days, suddenly says 45 files and 2 days and then changes back. What is going on? Dropbox is communicating over network at around 150 bps. There is no way to see what files are being synced and queued - and what direction. If the UI showed this, at least the user would be able to see if things seem to be right or not. Dropbox also restarted several times yesterday, doing 3 updates. So I removed it, cleared the cache and reinstalled. But is still syncing. Have checked for links and permission a month ago (running on Windows). Now it says 37 files +2 days - how is that possible? Something is clearly wrong with DropBox at the moment. In the past there were never such problems.
