Search doesn't seem to work

I've installed the troll module on Drupal 4.6.X and while it appears to work ok (no errors in the logs, I get a user listing and all the expected admin screens and links), I cannot search for a user.

Anytime I try searching (I DO see the user list completely displayed at the bottom of the page) by anything -- with or without wildcards, using complete usernames or email addresses etc., after I hit submit, I get set back to my default site page. No search results, etc.

I have made sure that the database tables have been created, and I am running as UID 0 (administrator). I made sure to download the 4.6 version of Troll, and I applied the patch noted in the bug database (editing line 383 -- or whatever that line #).

Any help or suggestions would be greatly appreciated.
