I loved the idea of using this for my mouse. In fact, it worked so well that it took over my whole screen and I couldn't for the life of me escape it and get back to my screen. I was unable to get to the preferences, my menue bar was gone as well as the dock. All I could see every time I moved that d*** mouse was those stars. It acted more like a screen saver that wouldn't budge rather than something that was supposed to trail the mouse. I'd like to know how to make it work as intended on my iBook G4 (tiger). Perhaps the deve has some thoughts on this.
