Skim PDF Reader and Note-taker for OS X

When you leave presentation mode after pressing escape, the title of the
resulting skim window still displays the page number of the page that was
shown when presentation mode was started. The displayed page itself is the
right one, just the page number is off.

Example: load PDF file, go to page 10, enter presentation mode, move up to
page 13, press escape to leave presentation mode, the page displayed is
page 13, but the title of the window says page 10.
