One thing that may possibly be tripping you up is that the
width of a window may change when it's shown, so your calculations
that rely on w() may be off the first time you use it. In
particular, on the XP box I'm using now, if I create a window
of size 100,100, its w() is 100 when exiting the ctor, but after
show() it's 115.
Of course, this may be totally irrelevant for you; I can't tell.
HTH,
Stan
