[Orgmode] Start the clock working weird

[Rodrigo Amestica]

I have a document that looks like this:

* doc title
** TODO to be done first
** TODO to be done second

I move the cursor then to 'first' and do C-c C-x C-i, I then get the following:

* doc title
** TODO to be done first
   CLOCK: [2007-11-26 Mon 15:13]
** TODO to be done second

Now I move to 'second' and do C-c C-x C-i, and what I get is the following:

* doc title
** TODO to be done first
   CLOCK: [2007-11-26 Mon 15:16]--[2007-11-26 Mon 15:16] =>  0:00
** TODO to be done second
   CLOCK: [2007-11-26 Mon 15:16]

I cannot understand why is that the clock is stopped for the first item.

I'm trying this on emacs 23 (perhaps that's the problem), any body out there on 
emacs 23 as well?

thanks,
 Rodrigo
