I am having a lot of defects which are created as ad hoc test runs. This means that there are no link to a subject. And when I try to filter on the value " Not'' " in the defect section in the field Subject I get a "Catastrophic error" Because of this error I can't filter proper on the value " Not'' ". I thought about placing a value in the Subject field, so I could filter on that value, but that does not work - even though I have unchecked the "Verify value" box in the Project Entitied section. I am not allowed to place a value in that field.

How can I get around this problem?
