Although it was only a short while ago that RIM released and update to BlackBerry Desktop Manager, we now have another one available to all you Windows users out there. If you open up desktop manager now you'll be prompted to go ahead and update to v18.104.22.168. No full change log is currently available but it is however noted that it's related to the BlackBerry PlayBook. Sadly, Mac users do not (as of yet) have any updates available to them but - it is coming. In the meantime, if you're a Windows users you'll want to grab the latest to ensure all is well.
