Why this item is listed in the fla (source code) section is beyond me. While listed as FREE, in reality it only allows 4 items to be listed unless you purchase the PRO version (50$) which allows a full list to be generated.
Though the author proudly proclaims the component to be "The best listbox component on our planet", in reality it is simply one of the most expensive.
It's worth versus coswt is for others to decide but I for one think users would do better with a google search for "flash components".
Being a flash developer, he should know better than to list this item in a category created for FLA files as this item CANNOT be edited or changed and includes NO source (FLA). It is simply a ruse to generate sales.
