I have a ibook, G3, running 10.2. when i download a program (like windows media ) it shows up on the desktop. when i click on it, it creates another file on the desktop. when i click on that one it says it can't find application to open the file. i assume that for some reason the download program isn't saving the program as a program, but rather as another file of some kind. this is way beyond my computing abbilities.
