Activeate a window by hovering over it (THE TITLE BAR) with the mouse

Hi,

Vista's feature in "control panel -> Ease of Access Center -> Make the mouse
easier to use -> Activeate a window by hovering over it with the mouse" is
one that I have been longing for since I switched from unix to windows.
However, the way it works is quite annoying. I would have to pay too much
attention to keep my mouse over the active window or otherwise another
window may pop up unexpectedly. Is there a way to set it up so that a
window is activated only if THE MOUSE IS HOVERING OVER ITS TITLE BAR (rather
than over any area of the window)? Is there a third party software program
to help mouse/keyboard easier to use? Any help is much appreciated.
