Is mousetrapping unfair?

Mousetrapping grabs control of your Web browser and won´t let go. It grays out the back button and all back lines of dialog boxes. It can also disable the X box on the top right of your screen. Any attempt to escape just brings up the same or another pop-up window or alert box. Sometimes a flurry of Alt-F4 hits permits escape by closing the browser. Sometimes nothing but Ctrl-Alt-Del works. Sometimes even that won´t work, and the power-off switch is your only escape. Mousetrapping gained public attention recently through litigation cases have focused mainly on trademark and unfair-competition theories of wrongdoing-as well as simple copying infringements under copyright law, because of the relationship of mousetrapping to pagejacking. What remains to be developed is a theory of copyright law liability that could satisfactorily resolve these issues
