When I start a powerpoint, there is an arrows box in the lower left corner. It just started appearing on my powerpoints and was not there prior to last spring. Not sure how or when a setting must have been changed, but I can not seem to figure out how to get rid of it. And it is on all my PPTs. This is in the way of some of my info and graphics for my students.
please help me get rid of it.

Thank you
Shannon
