PS: Is it so difficult to add some lines of code enabling AI remember maximized window pos ? I've read hundreds of posts asking for this.
Do you keep your system defragged? Have you installed and have active more than 150 fonts? When you say you aren't getting speed, can you detail the area more and times involved? What operating system?

Don't get me started on the file corruption issues..... I'll put that in another forum.
Illustrator 8's .ai format was based on EPS. Since then PDF is the base and, of course, the text engine in CS is far more sophisticated. I don't have many version 8 files still not converted to at least one of the higher versions, so I can't test that, but I'd be more concerned if your speed for opening and using version 10 or CS files was extra slow. They certainly aren't on my system, which isn't the most powerful out there today (it is a P4, 1.7ghz with 384mb RAMBUS RAM).

But try moving around the very busy sample map of Yellowstone in CS. Not bad. Kudos.
