EPS rendering strangely
I have an EPS file I created in Illustrator. When I open it in Photoshop at certain dimensions (enlarged from the original), some unusual elements are introduced.
Here you can see a thin yellow line that's not in the original:

And here you can see the "holes" in the foreground showing the background color behind.

I checked the original AI file in Illustrator, and no matter how much I enlarge it there, these unwanted elements don't show up--everything looks just fine.
Any thoughts on why this is happening and if there's a way to fix it? I wanted to send this file to a client, but I hesitate to do so if it's going to have strange problems at random sizes.
I'm using Illustrator CS3 and Photoshop CS5.
