How do I hide or re-size the Event Calendar in a CiviCRM Dashboard?
OK, so I had installed the Event Calendar extension from osseed, but had not installed the required JQuery Update module for Drupal. When I did that, and re-enabled the Event Calendar extension, now Event Calendar does not appear at the bottom of my CiviCRM Dashboard when adding a Dashlet based on a Drupal View. 

I still have the whitespace problem when adding a Dashlet based on a Drupal View, but I think that may be a setting to adjust in the Display settings for that View.
