update
Come on now! I am in AI and open a file to work on when a popup appears telling me that a new version of AI is available. However, when the update 'button' is selected nothing happens! There used to be a check for updates under Help yet that does not exist anymore. When it did exist it worked. So what is gong on now? More frustration with AI!
