When in a drawing, when I sketch>rotate some drawn geometry/text, it works almost perfectly. When I try to enter a number into the "rotate angle" it works fine. When I backspace, it works fine. But if I try to delete a character in the number in the box, it doesn't work. I thought I had broken my delete key. No, it just doesn't like to delete numbers in that box.
It's obviously not a big deal, but it is an interesting bug.
