Edited Issue: Scrollbar doesn't appear in "Source Mode" [7799]

Hi,

I'm usign the CKEditor v2.00.11 with DNN 7.0.04 and when I enter in "Source Mode" no vertical scrollbar appears but I have lots of code, so it should appear. When I copy/pas the code to a text editor, all the code is there.

Should I look at something in particular in my CSS that can cause this?

Thanks.
