How can you make that script update faster? It's pretty simple - I don't really see any scope for decreasing the timing. (<i>Increasing</i> it is easy, which is why I suggested putting enough of a pause to completely break the illusion that it's tracking the mouse.) EDIT: actually, I can see a way to make it track better: draw just the heavily highlighted row, and then fade out the surrounding rows more slowly only if the mouse is still over the same row.

I should point out a couple of things I didn't make clear for the reason of creating the demo, It was in response to a comment to A List Apart's original article in which a users mentioned case studies (I believe in the print world) that visual noise impairs responsiveness to tabular data, I wanted to show a simple and effective way of reducing the noise. As far as the flicker goes this could easily be solved with a bit of timing in the script, I will sometime this week come back to it and build something a bit more robust, for the moment though it was just to show a simple way of reducing noise and get feedback. Kind Regards, Christian Piper Hi Joe, Thanks for the comments.
