query for non resolved and either unassigned or assigned to me

Hello,

I'm running Service Desk 7.5 not service packed.

I'm trying to put together what should be a very simple query.  I want to query Incidents that meet the following criteria:

status is not closed

status is not resolved

current analyst is either null, me, or a recently departed employee

here is what I have in the criteria definition

Status.Title Is Not Equal To ( Closed )

AND Status.Title Is Not Equal To ( Resolved )

AND Current Assigned Analyst Is One Of ( me, otherperson )

OR Current Assigned Analyst Is Null

Advanced Criteria Conditions:

(1 AND 2) AND (3 OR 4)

When I test this query, I get no results.  If I remove either line 3 or 4, it works fine.  Any thoughts on what this query should look like to make it work?
