In excel, whenever I try to type in a cell, I must press the first key 10-20 times before it shows up. It doesn't show up delayed, as in it shows up with 20 a's, it just shows one. Once the first key shows I can type anything else in that cell, but when i hit an arrow key or click to go to another cell, I have to hit the first letter 10-20 times again. I have to click 10-20 times to click into a new cell as well. This just started today. I've tried restarting excel a few times, but It didn't help.
