That's a very recent dev build. To keep Vaughan's life simpler, mightn't it be better if we stick to the beta channel for testing this script? That way we know we're on a fairly stable build of the browser and there are fewer moving parts. I'm still on 4.0.223.16 (the current beta version) and the script is working fine.

I'm running Chrome version 4.0.237.0 and the script does not work at all.
I have other scripts that work fine, this one is the only one affected so far.
