Collapsiblock not working in Genesis subtheme

Hi,
I'm using Collapsiblock with Genesis subtheme. The module is not working correctly. However, it works fine in the garland theme. I've done everything I can to fix this ... see this posting: http://drupal.org/node/519136. I even commented out the "edit links" option like another recent posting for this project just mentioned.

Is there a certain width the blocks need to be to show the expand/collapse arrow? my block widths are 180px.

Any help is greatly appreciated. I've been struggling with this for days now :).
