This drives me bananas every time someone links me through DropBox. I actively dislike people sharing stuff to me with DropBox.

Would make sense to make for a free product but if people are paying and this is still broken, seems a bit stupid.

Actually... now that I think about it; what annoys me most is the fact that it pops up a login box. If it was just on the side not covering the content I probably wouldn't dislike it so much.
