Just noticed yesterday that initial window sizing is broken on
Windows for puzzles with status bars, because the initial call to
check_window_size is given the window size _without_ the status bar
and assumes that that has to be big enough for the whole thing
_with_ the status bar, so it shrinks everything by a little bit. So
now we resize the window to take account of the status bar before
calling check_window_size(), and the problem seems to have gone away.
