Just noticed that most of your earlier posts are about using Illustrator, not Photoshop. If your question
is about rotating an object in Illustrator, disregard my comment.
This was posted in the Adobe Illustrator forum so I would presume it's an Ai related question. Don't worry though, happens to me all the time.
That's exactly what I did. A plain un edited rectangle will rotate fine but if I add an effect, it goes berserk!
