Motorola Milestone XT720 :: Its Stuck Updating Applications?

For about a week now, there is an icon in the notification bar that my system is getting updates. An orange circle is on top of the icon and the number in that circle has climbed to 50. I only have about a dozen apps installed. When I pull down the notifications list and select this update list, the title is "Ongoing" and the apps are TweetDeck(Twitter, Facebook),... If I touch that line, it may go to the market or more often bounces back to the ome screen. How do I cancel what it is doing and stop it from continually trying to update apps. I have gone through all the settings and still no luck. God, what a stupid, bug filled OS.
