Hi Brian, thanks for posting your nodeeditor folder.

So here's the steps that I am doing. First I launched your node editor dialog, then I use Load and load in your VectorExamples.nod file from above (on post http://moi3d.com/forum/index.php?webtag=MOI&msg=7777.1668), then I push the Run button and those arrow objects appear. Then I close the node editor and they all disappear.

Are you doing any different steps than that?
