FLASH1296  On a (new) Mac running OS X 10.5.5 it installs - but that is all that it does.

Try to figure out how to use it. I could not get it to work. The on-line html help is Mac-hostile.

Dond't waste your time. The installed folder of AppleScripts are also non-functional.

There is no included "uninstaller"

That is too bad because the installer drops a LOT of files everywhere.

Spotlight only finds a few, as it does not search within System Folders.

I used "File Buddy 9" and was able to delete all of the files.

This is NOT recommended.
