Flash has stopped working in Google Chrome. Mac OS X Lion, Chrome 22, Flash works in Safari & Firefo

Flash player no longer working in Google Chrome -- Chrome Version 22.0.1229.79, Mac OS X Lion. Flash works fine in Safari and Firefox. Pages with flash freeze -- can't scroll (e.g, nytimes.com); on youtube, sound plays but the video windows are black spaces. This problem appeared Sept. 26, 2012. I was running Snow Leopard; updated to Lion in hopes this would resolve the problem, but the problem is still there. If I go to chrome:plugins and disable Flash, I can scroll around nytimes.com and the flash box/window just tells me to install flash.

I have tried: Clearing Cache and all other data in Chrome. Going to the Library in Finder and deleting the Google folder from Library>Caches, then uninstalling Chrome and reinstalling it. None of these have fixed the problem.
