So, the other day I downloaded something. I think we all have the same download stack on our dock, with the downloads that you downloaded most recent at the bottom of a one column list...or at least that was how my downloads did look. When I was trying to drag a download into a folder, I accidentally dragged my downloads stack off of the dock. When I put it back, the stack was now a grid, arranged alphabetically, so I couldn't easily find what I had just downloaded. And it won't even let me change it! How do I get it back to the way it used to be?
