This afternoon, working great. Tonight, I cannot load either my Google homepage or Gmail. It starts to load the page and then a new screen comes up: "Aw, snap. Something went wrong displaying this page. It suggests reloading the page- same thing happens.

Other pages load, but my user scripts (primarily Adsweep) are no longer working. What's going on here???

I don't know about your page loading problem but i do know that Adsweep as released a new version that supports the latest Chrome-dev update.

All is well now. I updated to the latest script from adsweep.org. I also found that one of the Better Gmail user script is no longer working properly (better_gmail__for_chrome-hide_invites.user.js). Once I removed this from my User Scripts folder, the Gmail page loads just fine.
