I have to agree with FA on this one. I have Asperger syndrome, and I find moving or blinking things going off in the corner of my vision to be seriously disturbing to my concentration. It has gotten so bad that I keep a post-it note near the computer, and if I see something I really want to read, and there is a distracting animation on another part of the screen that I cannot scroll away from, I put the post-it over the animation to block it off.
