Remove item from Context Menu
I've just installed and then uninstalled iconStiX again - just to see where the stuff was placed.

The uninstall is like this (see Readme.pdf in iconStiX.dmg):


  Throw away the following 4 items into the Trash:



the iconStiX program in your Applications folder (or any other place of your choice)
in your ~/Library/Preferences:


li.loos.trollin.iconStiX.plist
li.loos.trollin.iconStiX.LSSharedFileList.plist (if any)

a folder named iconStiX in your ~/Library/Application Support folder



  Empty the Trash.


BUT this doesn't remove the Contextual Menu Items - unless you reboot your Mac (I did that, and the items was gone).
