I have no idea. Could it be a video card limitation?
Try a much smaller file and see if that works.
It's not a particularly large file @ 1110 x 1328 px and 11.5 MB... Plus it's a file I've worked in (and cropped) before. This Mac just got back from Apple Care a couple weeks ago where it got a brand new motherboard too.
I did just get around the problem by shrinking the canvas to the right size. That worked.
By the way, since the last Adobe updates, my PS & AI both have been popping "Parser Module" errors up every time I try to either open an EPS file in PS or save an EPS file out of AI. Part of the same issue?
Thanks for your help,
