Actually I do use StuffIt on one of my other machines. Both softwares have their own aspects that I like, but Stuffit is good about opening a file in the same directory as the Zip, while you usually have to point Winzip to the place where you want it unzipped. I'll switch over to StuffIt for my Internet Surfing Machine and for Renderosity stuff. Still puzzled however why it suddenly started happening after having never seen it happen previously (?)
