I am running Chrome Version 32.0.1700.41 m Aura and while it is apparently considered a beta version, though I did not install it and Google has pushed it out to a subset of regular Chrome users before it becomes the latest version of Chrome.
I am having the constant problem of CCleaner corrupting my Chrome User Preferences file every time I run CCleaner. Obviously for anyone to proclaim this IS not CCleaners problem is sipping the corporate koolaid!!! CCleaner has jumped the shark if they don't push a fix out soon. I will not be uninstalling this version of Chrome but uninstalling CCLeaner and not coming back.
