Keyboard is lagging, typing so very slow, why?
I thought this was a browser specific, memory issue, but it's happening also in my Mac Mail app, when writing email messages. Why does the keyboard input lag, often having to wait several seconds while it catches up, and it also will misplace letters, putting them in weird order, and not how it's being typed. This is a very frustrating issue, and shouldn't be happening, as I have plenty of RAM. What could be going on?
