Applescript for window rotation?

Is there an applescript aficionado who can create one for me which would enable me to cycle between the open windows of any application? Or is this not possible?
At present I use the Fkey called ‘Send to the Back’ but it doesn’t work in all apllications.

Not possible. It may be possible for individual applications; each must support windows as a scriptable object. (Appleworks does; I don’t believe IE does, for example.) There cannot be a generalized Applescript for this because each applescript statement must be contained in a “tell app” block that directs the command at a particular application.
