I worked for a long time on something, and saved it. But I may have saved it from one of its subpatches. The reason I suspect that's what I did is that now, when I open the saved document, I am brought immediately to a subpatch rather than the main one.
Did I lose all my work, or is there a way to get from the subpatch to the main one? Option-clicking on the title bar is not bringing up a menu, and that's the only way I know to get to a parent window.
