I think the problem here is one of interface design, rather than a
programming problem.  There is no way in which you can cycle through the
windows based upon their order on the screen, as you change the order
when you bring a window to the top.  If you think about it there's no
sensible way to handle this.  Imagine a user in this position; he brings
the second window to the top with shift tab, and then goes away for a
day.  When he comes back, he wants to look at the window which is now
second, and (sensibly) presses shift tab again, only to get the THIRD
window.

The way I have coded this, is to impose another order on the windows,
(e.g. the order in which the windows were opened), maintain a separate
list in this order, and cause shift tab to cycle through this list.  If
you examine the task manager, I think you'll find that this is the
method that it uses.
