That is the corect behaviour of buffers.
Close means merely 'close'.
AKA get this buffer-namespace outta-my-face;
=OR=
Icanhaz some fun answering basic questions in the article-buffer
called 'gnu.emacs.help'.
list-all-buffers wil show you that "untiteled" still exists
in the namespace 'buffers' where all buffer-names exist.
If you do a 'kill-current-buffer' (C-x k) it will politely inform you with :
"buffer has changed , kill it anyway ? yes or no ?"
IF you DID_NOT change it by typing any drivel in it after creation
then it will remove the buffer-name-space from the memory, but if you
activated auto-save and waited long enough (1 ... xxx seconds) you still
can get it back from the auto-save-list with minimal (or even non) loss of data.
If you want to SAVE the buffer_content, you must ASK to write
the buffer to disk, and it will ask for a name when a file allready
exists with that buffer-name called 'untitled' or replace it, if asked.
In short, 'Close' is a non-destructive call in the buffer realm.
Some study of the emacs-lisp-buffer-behaviour should be a more
usefull timewaster for you.
