Hi, fellow mac people. I am trying to backup my Iphoto library before I install Snow Leopard (just in case). I do have time machine backing up my stuff also, but, I'd feel more comfortable if I could burn a DVD with my backup of Iphoto. Anyway, when I go to the "pictures" folder of finder, and select the I photo library, I then click on "copy Iphoto library", but nothing seems to happen. I was expecting some new window to open to ask me where I'd like to copy it to, but got nothing. So, I then thought that I'd first insert a blank DVD and then select " copy library", but still nothing. Am I doing something wrong? Also, does anyone know the difference between "copy" and "duplicate", because they are both options in this area. Thanks in advance. Dale.
