Even if I delete my iPhoto library and create a new one, MacDaddy always shows each event twice as shown here: http://effinthing.com/~dfelicia/macdaddy.png
The problem is that the most recent version of iPhoto now presents events as albums too. To workaround this, go into the MacDaddy settings and goto the iPhoto tab and change the Display option to iPhoto albums. This will get you back to what you used to have, both albums and events mixed together, but only once.
(Folks that want albums without events however are kinda screwed unless iPhoto fixes things.)
