All of a sudden I was typing in a field and the letters started moving. The cursor moved to the far right of the box and when I typed letters they would float left with spaces between each of them. This happened anywhere I would type text regardless of the application. Assuming some process was messing things up, I rebooted and now cannot log into the machine because it's doing the same thing. I type to put in my cursor name and the cursor moves to the right of the box and as I type the letters move off to the left out of view with spaces between them, the spaces depending on how much I pause between typing. Has anyone ever heard of such a thing?
