Awesome module! Minor Errors on install with Drupal 4.6

You are a life-saver! If you track my posts, you can see that I've been desperately searching for this functionality! Thank you! Thank you! May I some day learn the art of PHP and custom modules!

I do have the following error when I first view the initial node-list page (after configuring the module):

ksort() expects parameter 1 to be array, null given in /home/gov/alpinecounty/WWW/drupal/modules/nodelist/nodelist.module on line 94.

The error seems to vanish after using the node-list page and then returning to it.
