SO I added the "Extensions" stanza to my xorg.conf file as you suggested but I
still get a non-functional COOT.
FYI here is my xorg.conf file:
# nvidia-settings: X configuration file generated by nvidia-settings

The main COOT window pane displays with all the menu items but the contents of
the window (i.e. the really important stuff) just shows a ghost of my desktop.
These are the errors that are output from the terminal:
