How to disable autoscrolling to textareas?

After i putted several textareas using ckeditor on my html form I noticed strang thing. My html form is pretty long and it takes 2 screens. After page loaded browser automaticly scrolls to ckeditor textareas

This happens only in Firefox. IE, Opera doesn't have such effect.

As soon as i delete textareas scroll doesn't happens. Is it ckeditor feature? If so, how can i disbale it?
