Scrolling down a big file with Dreamweaver MX

I'm trying MX after using DW4 for some time. I'm editing a big file of headlines and links to stories. DW4 lets me simply scroll down to the bottom. MX shows me just the first screenful plus a few lines, and I've spent a frustrating time trying to get to the rest. It's all there in code view, but not in design view. I'm obviously missing something ridiculously simple. Help!
