Can't drag files from drafts to header bar[NOTED]

I’m just taking the tutorial and followed the instructions to drag and drop files from the left draft list into the header bar as an illustration of what Scriv can do. Well, as soon as you grab it to drag, that’s a selection, so it changes the header bar anyway, so that doesn’t do anything different than just selecting the file would, so it’s really kind of moot anyhow.

What’s more, my Step three file seems now to have hidden itself behind the Step 2 file in the left nav. I can get it in the header bar if click the arrows, though.
