When I go to [All Tools -> Organize Pages -> Split, it displays a pop-up to enter how to split it. I generally need to use the "Number of Pages" option with it being every "1" page. When I type the # 1 with the key on top of my keyboard, all is well. However, when I type the # 1 with my number pad, the letter "a" displays instead of a 1. The same applies for 2, 3, 4, etc.. It will display b, c, d, respectively. It's not a deal breaker, but it doesn't seem to work as intended.
