      If ,indeed, you are asking, "Why hasn't anyone come up with this before?".
      I think that the problem here lies in the window design.

      I create a window with 6 controls in it.
      I get them all right where I want them.
      Then when someone with a different screen
      res runs my program, everything is crowded to
      the upper left corner, or running off the right
      and bottom sides. This is because controls are
      normally located from the upper left corner.
      It would take an enormous amount of time to
      calculate all possible window-opening sizes and
      proper placement for all six controls.
      Now it is possible that using a screen res dependant
      variable in the control location calculations you might
      be able to minimize the amount of code it would take
      to properly locate them. My guess is that for ease of
      programming, most programmers hard code a window
      size. This is not to say that the user couldn't resize the
      window. I currently disable all window resizing except
      'minimize' and 'restore', to prevent this sort of thing.
