Near as I can tell, you could hit the random number generator a couple of
times and use whatever numbers come up. Here's why - the Logon input field
looks like this:

       <input NAME="Logon" ALT="Log On" HEIGHT="20" BORDER="0"
              SRC="some_image_link" TYPE="image" WIDTH="78" />

According to this:

   http://www.w3.org/TR/html401/interact/forms.html#input-control-types

an input box of type=image causes the browser to return the (x,y)
coordinates of the mouse click to be returned. As long as you roll random
numbers that fall within the image size, you should be OK.

I dunno why the app would want the mouse-click coordinates - maybe it
ignores/discards them, maybe it initializes something with them, maybe
something else completely.

Of course, I could be all wrong... :)
