As I just wrote in my reply to Dave, internally we know very well which window
an action is to be performed in. This window is the window that'd be in the
foreground after the previous action, if nothing interferes with the system
while the script is being executed. A common exception is when you enter
commands in the interactive interpreter: say you write
>>> start("Notepad")
The Notepad window opens, but for you to enter the next command, you have to
switch back to the interpreter window. If you do that, and enter
>>> write("Hello World")
then we remember that you were previously working with the Notepad window and
activate this window before performing the key strokes to type "Hello World".

Those are also my favorites at the moment :)
