Flash back to 10.2: I had noticed disappearing disk space on some of the computers where I work. I don't know what, how, or why, but when I booted into OS 9, I found the OS 9 trash was full of temp files. Photoshop 7, Illustrator 10, were native, but we use some classic applications (Quark 4, Pagemaker 6.5, Streamline). I haven't noticed this in 10.3.1, but then again, I have 30 gigs free.
