There are two widget folders on my computer, one in the library of my user folder, the other in the library at the /library/widgets level. Both have widgets in them. Widget, The World Watcher only installed it's folder action on the one in the user folder so I manually attached it via folder actions to the other. It did warn me about the zaptastic when I tested it on the provided website and offered to delete the offending widget from my desktop, which also seems to have worked. With the exception of having to do the manual install on the root level library/widgets folder this works great.
