i have been using vista for about the last year and had many problems with it so i bought and ibook g4 today to try it out. i can't do anything with this thing, its a paper weight that i can check my email with. i can't open any files, i can download limewire but apparently opening it and running it is too much too ask. i sent the dozens of useless files that had been collecting on the desk top to the trash can and i guess i deleted something important because it won't open anything on the dock. i am now reinstalling os x. i would really like to get use to this thing and give up vista, but right now i don't think its going to do what i need it to do. how do i open a wma file for starters?
