Good point. I guess my only other question is - how is the callback 
happening? If it's an ajax callback then you wouldn't expect it to come 
in for a re-render pass, therefore the lightbox would never appear.

Other than that, it sounds like the scenario is getting kinda weird - 
suggesting that perhaps something is wrong.
