Clip the flight feathers on one of her wings. It'll throw her off balance and keep her from going up and over. Hopefully, by the time she grows them back (her next hard molt,) she'll be out of the habit. If not, it's time to break out the scissors again!
Also - try putting in a swing, it may be just enough of a boredom breaker to satisfy her fidgets. They're easy to make. Just suspend a perch using nylon rope or clothesline cord (do they even make that stuff anymore? I'm still using my stash!) Chain can snag toes and cotton/natural fiber rope holds yuckies. Nylon is easily washed and can be bleached.
