When clicking on the sponsor banners on the top right corner, it goes to their site on the present window.
I think it would be better for it to open in a new window, so that once you're done with that, you can easily resume where you were browsing here.
Just a suggestion

I agree, on web sites I do, all external links open in a new window. You'll notice that links within post on message forums also open into seperate windows. It's an easy fix.

Just haven't gotten to it yet....

I know how it is!!!
