rps, there's a "downside" to the suggested solution of hiding the website button (under the circumstances).
Some people may believe that MA is only a screensaver, and will therefore (without some complicated instructions) NOT be able to get to the website button.
That's relevant to the update issue.
Yeah, I thought of that; but the fact is, if the user has configured their system to require a password once the screensaver has kicked in, then [interactive] access to the web is pretty much a non-starter. The way to handle access to the web is to have the MA3 install program add a shortcut to the start menu that takes the user to the website.
Also, I disagree with your assertion that people who think MA is only a screensaver will not be able to get to the website - the website button *would* be available through the screensaver settings dialog.
