My Calculator app (the bog standard one) used to behave itself, and used to pop up just as the calculator (no ticker tape) I then pressed 'show ticker tape' just to see what it did, then hid it again. I opened to Calculator app again and it had the ticker tape , so i hid it again and closed it only for me to open it again and it had the ticker tape!
I know it is small, but it is a little annoying. Thanks
