Using the latest build, the new Chrome flash cookie cleaning wipes out the flash player settings too.
also the new Bing cleaning clears all the icon's from Bing news etc, the only way to get them back is to uninstall then reinstall.
Just a little heads up with the bugs above.
I love ccleaner, been a user since it was first released by, I think the name was mad dog (Mr G?) posted it.
