I was doing this tutorial using CS5
http://vector.tutsplus.com/tutorials...ype-treatment/

Evrythings fine till Step 9. But I get stuck with STep 9.

When I draw the five ellipses on top of the ladybug body an group em together an try an intersect them Illustrator gives a pop up message saying "Filter produced no results, please select two overlapping paths"

Any idea why? I tried everything I can think of but no cigar
Maybe CS5 is different.

That's fairly basic AI functionality, I don't believe it's a CS5 thing.

Have you tried zooming way in and making sure your paths are overlapping?
