When I use "C-h f myfunc" I get the docstring in the *help* buffer.  I can close the window

with "C-x 1". 

But tring to close the *help* buffer does not work.  I press on the "Red Cross" and the

*help* buffer remains present in the Buffers Menu Bar.

If I press the "Red Cross" on the *scratch* and *messages* buffers, the two buffers

get removed from the Buffers Menu Bar.
