Problem resizing a window and button placement

[Steve GS]

Musta misstit....
I had thought of that before I
started the discussion but
figured it would take more
code than it finally needed.
I guess I was also
variable-dependent thinking
that I would need the result
elsewhere in the code.  So
far, I see that I don't need
the value.

Then there is that discovery
element: Why is my original
idea not working? I still
cannot pass the value back
from the function.  What is
different about this function
that others would have given
me the value?

Right, just what I wrote
earlier:

"have the function that
responds to the resize event
perform the action that you
want"
