- make it so you can click on the box to make it stay up

    - It doesn't look trivial to get BeautyTips to behave like this.

          First: you need to disable the normal mouse-out handler
          Second: add a new handler to make it .btOff()   (click elsewhere maybe?)
          Third:  only AFTER the box has been closed (see 'Second'), then we need to restore the
                  original mouse-out handler


                (perhaps we could add our own mouse-out handler, that first checks a flag before
                calling .btOff(), and that flag could be changed via the click-handlers
