Your example file does not cause my laptop (Mint Helena, which is built on Ubuntu Karmic; dual core Intel processor) any problems. Response to the cursor keys is fine. Of course, I do have slow reflexes ... :-) If you google "LyX 1.6 slow scrolling" you'll find a number of previous messages about scrolling issues. As I recall, in most cases either switching to a different version of Qt or tinkering with the Xorg drivers seemed to help. I can't say first hand, since I never experienced it myself. /Paul
