Ok, ok…. so I should have built-in an auto-update, ClickOnce would have been easy enough…. but anyway…. I’ve added many features to the Xbox to Twitter application, including support for only updating when the title being played changes, not showing popups and even a preview of what your twitter updates will look like once they are combined with your template.
To update, uninstall the client using your Control Panel then click on the install link and reinstall. You should see the new and improved options dialog where you can choose to update only on title changes and also turn off the lower-right notifications if you wish.
