I'm running Chrome dev. again. 7.0.503.0 LastPass is working again. Also it's not shy about honking. Running nothing but Speed-dial it's using 8 processes.

The one I like most is --enable-fastback which seems to side-step that annoying feature of fetching the page you were just at instead of pulling from the cache.
My favicons work. So far it seems to just kick ass with no side-effects. But this is the first day.
Here's a link to the dev. channel:
