When I right click on any node while editing a workfow I see a menu option "Open Template". This provided the dialog box shown above. It also allows me to change settings and click OK to save them. I don't want to make changes to this unless I understand it, but it looks like it could be handy. We are running 6.9.1 patch 9. And yes I can drop any node on the workflow and I can open the associated template.
You shouldn't see these screens. What node is this on? These are screens internal to the node type and end users shouldn't be seeing these. If you drop a new fulfillment hander node on the workflow and look at its properties, do they look the same?
