How to hide the "trimmed version" from the preview page? When I "preview" a node add/edit form it shows a "trimmed version" and a "full version". I don't want to show the trimmed version.

The fix suggested for D6 doesn't work for D7. Any ideas?
You tried CSS? 

.preview h3 , .preview .node.node-article.node-teaser {display: none}


In my case the content type is an article and worked.
