About the stop of development\distribution of Y'z Dock
I received the warning of piracy from Apple Computer, Inc.
I admitted that "Y'z Dock" was imitation of "Dock". And I decided to stop development and distribution of "Y'z Dock". This stop is lasting. It is NEVER resumed.
Moreover, I do not permit re-distributing "Y'z Dock" by others. Please NEVER re-distribute "Y'z Dock".
And this warning act by Apple Computer, Inc. is lawful and just. Please NEVER slander this warning.
Thank you for your understanding.
I apologize to Apple Computer, Inc. and the persons concerned.

So, the answer is yes.
I didn't really like YZdock. It was somewhat glitchy, atleast for me, but even when it did work, it was more of an annoyance than anything. I had to shut it down before playing a game because it'd reposition itself into the game window, even if I had it docked at the bottom or the right (windows for games start that top left corner so it should've been made to not interfer). It did a decent job of immitating, but it really wasn't usefull.
