in the previous beta, preview crashed a lot for me, especially when trying to edit pdfs. then one afternoon...i downloaded the manual for a blender. preview crashed when opening it. the weird thing is...now, every time i bring music into itunes without art, the default image is...the cover to that manual. it' sorta funny... anyone know where this file is stored, so i can change it? or have an idea on how to fix this? i can paste over it, just...hate seeing that image every time i import music (i make music, and use itunes a lot for this).
