Thanks, Jan.
Actually, the trouble was that I wasn’t including the admin_init hook stuff, which I thought was optional. Without including it, though, the metadata array was being filled BEFORE the init() function was called, which clears the array. That is all fixed now, though.
Nevertheless, I’m really glad you you shared that tip with me. I definitely want the option on the post-new.php pages, so your fix really did save me a lot of time and hassle. Thanks!
