I'm completely new to OSX, so forgive me if this is a stupid question. But recently, my Downloads stack is no longer a "Stack" anymore... It's still next to the trashcan, on the right side of the dock. But whenever I click on the Stack, it just turns into a translucent square, with an arrow pointing down. How do I get it to "spring" open again? I don't know if I somehow accidentally changed a setting or something, because I've been trying to mess around with OSX. Also, on an unrelated note, I moved my Dock to the left/right side to see if I like that better. I decided that I like it on the bottom, but it's become highly reflective now, instead of being smoky or whatever it was. Anyone know how I can change it back?
