The text window is used to display both plain and html text,
depending on the format of the input. It has two scrollbars,
plus a little '*' button in the corner which is the same  as
the Reload button.

If you would like to see the input (source)  text,  use  the
Opts menu, and select Show Source Window.  A second, smaller
window will pop up that shows the unprocessed input text.
