Note that the desktop window with a handle of 0 is the root desktop
window, it's what is present if explorer dies (or is killed). The
usually visible desktop window is the shell desktop window. I know
there's a windows API to get that too, but I'm not sure if jaws
script mirrors it, and I'm too lazy to go look.
