Problems with external links

Hello, I have problems when I try to insert an external link into my textarea with ckeditor. For example, I want to insert a link to google.
It might be something like this:

<a href="http://www.google.com">Google</a>

but when I insert it the link is:

myweb.com/"http://www.google.com"

So I cann't insert links to external pages. Anyone knows how to solve this problem?

Thank you
