Comment 4 for bug 36013

(In reply to comment #3)

Thanks so much! This bug does a much better job keeping up with me. However as I type this bug in this box, it does not bring hte focus back correctly when it reaches the end of a line. Instead it appears to out of bounds and loses focus completely. The product is much more usable however to the gnome-mag screen magnifier.
