Take a look at this:

  buttonimg  = owner.getImage(owner.getCodeBase(),
owner.getParameter("BUTTON"));
  int w = buttonimg.getWidth(this);

why is w -1 here, and 437 later.
when does buttonimg.getWidth(this) return the right value, is it possible to
wait until its correct?

is it valid to do something like this:

  buttonimg  = owner.getImage(owner.getCodeBase(),
owner.getParameter("BUTTON"));
  while (buttonimg.getWidth(this) == -1 || buttonimg.getHeight(this) == -1);

or is there a better way?
