Whenever you resize the page view, click on test click mode, or do something the program doesn’t like, a notification box pops up and blocks the work area. It fades away in a couple of seconds, but for the period of time it’s there, it’s a major pain in the butt. Also, there’s no need to have it repeatedly appear in multiple instances one after another.
Really, this “feature” should be disable-able by by power users, maybe substituting an audible beep or something. At the very least, please move it outside the work area, like up to the menu bar area.
