XPLODINGBOY  I just launched the previous version (4.1) of this utility and I was prompted to update to the newest version, so I did. The previous version was free, and the new update is paid shareware. When I was prompted for the update, the cost change was not mentioned.

I think that utilities released for free should remain free with very few exceptions. If a developer wants to add additional functionality to their free utility and charge for that different utility, that would be great. Just have two versions, free and paid more functionality.  
(Version 4.2)
