So I spent a couple of hours beating my head against the screen

yesterday trying to get the Single Post Template feature to work on my new Genesis-based website with a latest version of Wordpress (3.2.1). This is what I'm referring to:
http://www.nathanrice.net/blog/wordp...ost-templates/.
From my research I found one obscure post about something changing in the new Wordpress core, which kills the plugin's functionality. Essentially the option for the drop-down menu within the post is not showing up at all.
Here's the potential good news

: Nathan Rice - the genius behind the plugin, is actually a developer with Copyblogger Media and I'm hoping that he could figure this out for all of us. This is more of a plea, rather than a request.
Objective: to have property listings show up correctly on Agentpress Genesis, as well as regular blog posts.
Please help!
Yours,
Svet
