author not showing after uprade to 1.2.2

Try playing with some of the code in postformat.php. As an experiment I just tried renaming the post-thumb and thumb-shadow classes like the following line.
That took out all the effects. Just renaming the thumb-shadow class left the fade in but took out the shadow.

This is the kind of playing around this theme makes easy as you can make changes to a virtual file and then hit the, in this case, subtemplate-postformat button on the bottom to revert to default state if you don't like the results or made a mistake.
