I'm using Apple mail on a new mac pro, Leopard and all apps are up-to-date. I sent myself some Photoshop files from work but when I download through my Gmail account setup through Apple mail, the files won't open and show a zero kb size. However, if I open Gmail in my browser, login, and download the same files from the same e-mails, they work fine. What gives? This happens everytime and it's very annoying.
