I am using the latest version of CCleaner 3.05.1408, and noticed that the list of websites under "Adobe Flash Website Storage Settings" is not getting deleted/cleared. I have "checked" Adobe Flash in CCleaner under Applications -> Multimedia.
The Website Storage Settings can be viewed/changed using this URL: http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html
Not sure if this a known bug and if it is being worked upon.
Thanks!
