Title: Keep track of the handle of the first window. Fixes #2805.

See #2805 for discussion.

Rather than track the current window as we switch from window to window during a session, I think we can get away with just grabbing a reference to the first window created at the start of a session--that'll always (I think?) be the one we want when the dialog is gone.
