It works fine for a while then all of a sudden it won't upload anymore. I still have space but it keeps stopping and starting and stopping. Also it starts by uploading two files at a time then stops and leaves those files un-uploaded and starts a new file, but this time only one file gets uploaded at a time. So I bought more space same bloody problem. People are depending on me. Dropbox is lazy and likes to fail its downloading either at start, mid and most annoying end of download. Fix!!!!
