iOS textarea stops working after scroll

Question

I've got a strange problem.

For some reason when I tap into my textarea and then start to scroll, then want to type into the textarea it does not work.

Any ideas what the problem could be?

Edit

This only happens when the keyboard is up

Edit

Textarea is inside an absolute positioned div

Answer 1

After scrolling ends try this

if (!yourTextArea canBecomeFirstResponder)
     yourTextArea.enabled=YES;
    [yourTextArea becomeFirstResponder];
