hi just got me a 13" MBP 2010 (Cheap i may add) anyway having no problems so far.....well apart from one i remember on my old white macbook/mini i could change the sound that Mail made when i received a new email. well i have changed the sound, added my futurama bender wav, also as an mp3 but when i get an email its silent and no sound is made! as soon as i change it to the default mail sound, it makes a noise! How do i get it to make the noise i want it to? EDIT: i have highlighted a couple of items to delete, so i highlight them and press the delete button. but when i do it plays that futurama bender mp3? what have i done wrong?
