[Evolution] editing recurring events

[Marc Williams <marcw onlymooo com>]

I just grabbed Evo 1.04 off of Red Carpet.  So far, so good.  But I
noticed something that I'm not entirely sure is new; it might've been
there in previous versions.  I'm not sure.

I can't seem to edit just one instance of a recurring event.  I can
*delete* just one instance.  But when I attempt to *edit* an instance
and then save, the edit appears to apply to all instances of that
event.  

Am I doing something wrong, is it a bug, or is this the intended
behavior?  Thanks!
