Node: Distinct filter not over-riding random data sort.

Hey,

I know you guys are quite busy with this support que, so I'll try to make this as quick and simple as possible.

I have a view which returns nodes based on a few filters, none of which are important except for the Node: Distinct filter, and sort data randomly, under sort data. Lets say I have 10 nodes which I want to display randomly in a block of 5. So I set sort criteria to random, figuring that this would make it work. The problem is, nodes repeat themselves in the block, they aren't all unique. Thus I look at the Node: Distinct filter, which I assume from its description ensures that every node appears only once.

The problem is, that its not working. If sort criteria is set to random, the node: distinct doesn't seem to work. Remove random, then it does. But then nodes don't appear randomly. How do I force views to display a random number of nodes, as set by the parameters of my current view, but display a node only ONCE in the block. (I.E. Once a node has been randomly selected out of the applicable nodes, ensure that it is not selected a second time).

Thoughts?

Thanks!
