I recently bought the new pro, lion included. I accidentally deleted the downloads stack and when I re-added it, it was not the same stack that I remember. I can no longer move files out of the downloads folder, only aliases. How can I remove the original files from the downloads folder/stack so I don't get that folder cluttered with a million downloads...I am not the most technologically savvy person either...so this could be a simple error on my part.
