so apple would get royalties from microsoft, mozilla, utorrent, avast, AMD, Sun, google, and just about everyone else that uses transparent dropdowns as part of their navigation process.
seems that these companies think the best way to survive these days is to A) not have any significant innovation and B) to lock out those who can innovate. In essence, playing "keep-away" from weaker people as if this was all taking place in high school.
It may now be time to come up with a new method of navigating programs that do not use semi transparent dropdowns.
