Just upgraded to Lion last month and I'm having this problem with Preview. Most of the time when I open a picture on my desktop with Preview, it will not only open the selected pic, but 2-3 other recently viewed pics as well. They can be in the trash, the desktop, or inside a folder but preview will open them anyway when I haven't selected them. I assume I have some kind of feature or option enabled in Lion that's doing this but I can't figure out what it is. Anyone know what's going on and how I can fix it? It's very annoying.
