Christopher, thanks for the reply. I've tried featureAdded, along with onFeatureInsert, and I receive the follow error: this.point has no properties: this.point.destroy(); this errors gracefully in FF2, but not in IE (pick a version). I've modified an example from the examples page to describe my problem (and error):

And again, any help for this newbie is appreciated..
