Users who want to control or investigate Flash cookies have several options, according to reader Brian Carpenter:

Windows:
* Better Privacy extension for Firefox -

* Ccleaner - http://www.ccleaner.com/

Mac OS X:

Where to find these flash cookies:
* Windows: LSO files are stored typically with a “.SOL” extension, within each user’s Application Data directory, under Macromedia\FlashPlayer\#SharedObjects.
* Mac OS X: For Web sites, ~/Library/Preferences/Macromedia/FlashPlayer. For AIR Applications, ~/Library/Preferences/[package name (ID)of your app] and ~/Library/Preferences/Macromedia/FlashPlayer/macromedia.com/Support/flashplayer/sys
* GNU-Linux: ~/.macromedia

Thanks for the "heads up". These intrusions on privacy are worse than drug test and airport security in my opinion.
