I think you're going to love this. I went to BestBuy to tell them how crappy this computer is and when i got home i tried to export the file and low and behold, when i uncheck Anti-Aliasing in the export dialog box, it works?? I ran several tests on (2) files that were 85MB each and it worked in 72, 150 and 300 dpi.
Have you a clue as to what is going on here?
Thanks for all of your help!
