Hey Terence,
Are you forcefully checking for updates on every start? If so, you shouldn't. Instead use the "DaysBetweenChecks" property and the UpdateType property.
Today when I run it, all it displays is the initial "checking for updates" message, and then nothing. Just a blank area where the message was previously displayed.
Does the animation still show? Is the AutomaticUpdater just disappearing or is it "sliding" closed? What happens when you manually check for updates?
