In Lion, if I do a Restart or a Shutdown, a dialog box pops up asking me whether or not I want to close certain open applications. But after a couple seconds -- before I can select the appropriate option in that dialog box -- the shutdown sequence continues. I vaguely remember seeing something about an option in Lion which controls this behavior, and which will delay the shutdown until I have enough time to respond to that dialog box. However, I can't recall where I saw this ... or even whether I actually saw this! Does anyone know what option in Lion that I'm talking about? Thanks in advance. .
