I opened up iChat for example...and the application then wants me to sign in or signup for .mac or whatever. Well I don't really want to do that I just want to close the app. But there is no red button to tell the thing to quit. I tried command-click and option-click and ctrl-click to see if it would give me an option to close the app. But no go. Boot Camp Assistant has the same behavior. I open it just to see what it's about. But then there is no way out. Ease of use?
