Once Again Great post Stormy,
Many people overlook this as there not aware that adobe flashplayer is logging and saving info just like a cookie. Only unless you visit the "settings manager" will you be able to clear out everything. I've tried at times setting the amount of space to "0" not store common local files and what not, but there are sites that need flashplayer user space. But I visit the settings manager at least twice a week and clear it out.
Here's an interesting experiment regarding local-shared-objects "LSO's". Go to the site linked below and Follow the instructions about moving the box and refreshing the page. Then go to flashplayer manager and clear all sites from the "Website Storage Settings panel" then return to the linked LSO webpage and the blue box will be restored to the upper left corner.
