You need to move the window up a bit. I have the same problem when using my laptop and use a handy wee program called Altdrag. Basically it allows you to simply press and hold Alt then click and drag the window. Do a google search, and you'll find a link. I had posted a creationkit.com page link before, but it has been moved.. sorry.
