I've seen a couple people saying that safari quits completely when the window is closed. I believe it is due to a plugin, because console told me the application "Stoplight" had something to do with it. Stoplight had closed because the window wasn't active any more, and it quit safari. Stoplight is a tab app. If you want to drag your window to a corner like windows except anywhere on the screen, use stoplight. A lot of people were wondering if there was a such thing as tabbed finder.
EDIT: When I said stoplight, I meant stickywindows. I forgot what stoplight even did. Stoplight is NOT a tabbed finder utility.
