This may sound like a strange request, but many times when I've been in flight or in tower, i've gone to click on something on the clipboard, and accidentally clicked on 'Website Help', minimizing the game. A good percentage of the time when AH minimizes to bring up AH home page, I get discoed, or AH won't pop back up (because my computer's weird I guess)
So I think when you click on the Website help button, a little checkbox should appear asking if that's what you want to do.
