I have searched this forum and the internet. My number pad on the right side of my keyboard works with everything EXCEPT the calculator. What did I do? cannot find anything anywhere to address just that. The numbers work fine everywhere else. I did all the jumps to make sure on the system pref and the mouse off, holding my tongue just right and jumping five times...hitting the option key five times, the fn button and the clear button. the number work everywhere but on the calculator. HELP?
