The worst thing was that, after I had "removed" Change Properties Now, my System Tray icon for Explorer no longer works right. When I click it, I get the message, "C:Program FilesChange Properties Now! refers to a location that is unavailable. ..." This means that CPN has altered my registry to run some CPN program every time I start Explorer.

The shareware (trial) version doesn't allow you to change any properties. The Website says that with the shareware, you can't change the Hidden attribute, so I installed it because I wanted to change the Read Only attribute. Turns out, that's not available in the shareware version either. The directory navigation pane only displayed about 15 characters, and wasn't expandable, so you can't see the full directory path until after you've selected the directory. When you try to select an attribute to change, you get the option to register, and nothing else.
