Happens to me all the time. There is nothing worse than making the effort to type out a long post only to find that nothing happens when you click submit. At my end, the submit button on the Quick Reply form often does nothing. So I switch to the Full Version and click submit there. Sometimes it goes through, but more often than not there will be a long delay and then it'll say there's been an error of some kind.
Either the forum software is crap, or Cakewalk's server is crap. I just wish they'd sort it out. Remember how happy we all were when they updated it recently? We thought it would be an end to all of the old forum crapness. Ha!
