I am no longer able to change the height of scale bars in ArcMap 10. I used to shorten a scale bar by pulling in the frame resizing tabs on the top or bottom of the scale bar (see attached image). This is no long functioning. Changing the height properties on the "Size and Position" tab of the scale properties does not change the height either. There are many instances where the default height of the scale bar isn't appropriate for the map layout. Is there another method of changing this height?
