properties box not viewable

Hi,

I've been using mockups for the last couple of days, for my new startup and also so I can write a good and fair review.

One thing I've noticed is that if I move an object down the page and scroll down, I have to scroll back up to adjust an items properties as the property box is located in the top right corner of the document, rather than the window.

Is there any way you can lock it to the top right of the 'window' instead so it scrolls down as I scroll down the page?

Thanks
