I was using the 1.4 version. Today I updated to the last version but I can't display the "Post Expirator" box in the Screen Options and I can't move the box in the position I want. It's back at the bottom when I'm back to the post.
Here is what I had before http://screencast.com/t/aI3TrJM9eS
now I don't see the "Post Expirator" in the screen options and if I move the box around it is back again when I'm back to the post.
Please let me know if I need to do something to let it work in the last version.
