Wordpress Custom Post Type "Read More" problem

I've created a custom post type made with this tutorial. The problem is when I try to display a part of the post it works exact the opposite way!

Post text:

You should see me!
<!--more-->
Not me. At least not yet.

PHP code:

<?php the_content("Read more...",TRUE,''); ?>

Should display 开发者_运维技巧something like:

"You should see me!

Read more..."

But it displays:

"Not me. AT least not yet."

And no "Read more..." link.

What's going on?

I was also having same problem. After a detailed observation I found that read more tag doesn't work on template tags. See here

The quicktag will not operate and is ignored in Templates where just one post is displayed, such as single.php.
