[Orgmode] Repeating appointments

[Karen Cooke]

Hi 

I have an appointment scheduled like this:

*** TODO Library 
     SCHEDULED: <2008-02-20 Wed +7d 10:00>

When I mark it as done it loses the repeater and the time:

     SCHEDULED: <2008-02-27 Wed 00:00> 

I'm using 5.21 on Emacs 22.0.50.1 as part of the Carbon 
Emacs package (Aug 2005) for Mac OS X 10.3.9

Is there a way to have a timed repeating task?

Thanks
