Looking for some help please!

No matter what I do I simply can't get the treelist column filters to work. I've even tried a new form with just a basic treelist and used the exact code from the Nevron example (which works perfectly).

Can anybody think of a reason why the below won't work for me?

Dim filter As NTreeListColumnStringFilter = New NTreeListColumnStringFilter("find this string", True,Nevron.UI.CommonStringOptions.Contains))
m_List.Columns("From").VisibleFilter = filter

I've tried it with different columns and different values, numeric filters, everything I can think of. After executing the above no data is filtered out.

Any ideas?
