Perhaps someone knows this. Is it a bad idea to just drag a program into the trash? Does that leave things behind on the drive like it would on windows? Is there another way to uninstall it so it's clean? The same with install. If I firewire my powerbook to my friend's and he copies a file over to his computer, sometimes it doesn't work. Do you have to download from the originial website or install from a CD always? If not when do you know it's not necessary? Sorry for all these silly amateur questions - I just got my powerbook a week ago and have been slowly figuring things out.
