Borders / frame around paragraphs in Internet Explorer

Hi there,

I have a problem — of course — with Internet Explorer (8). IE creates weird borders around <p>-Tags that lets you move and resize the whole paragraph. This is very annoying. You have to click the paragraph 3 times before you can actually type in it. The borders look like this:



In the online-demo on ckeditor.com there aren't any borders in IE, although there are p-tags. I'm wondering how you can get rid of these.
