I have been fiddling with the code analysis settings, and obviously clicked something I ought not to have clicked, and now I have this rather obtrusive help display occupying half the screen. Is there any way to get rid of it? (Closing down and restarting doesn't.)

Edit Following the suggestions given, Windows->Reset Windows Layout doesn't get rid of the screen, but shutting down the machine does so, until using the Action pull-down while editing a ruleset causes it to reappear.

A temporary solution to this problem is to restart the machine.
