I'm sure that was fixed very fast, but I checked for that only today, and now it works. The extensions are nice, I've already added one that will auto-replay YouTube videos, other that will shorten my links via bit.ly, and other one that helps me posting to my blogger account. Yes, that Chrome is a Beta version (4.0), but it works exactly like the stable one (3.0), with little problems so far (these were found even on stable version).
