Am I confused or is the UIBuilder?

You are looking at it wrong i'm afraid. You can't really use the run mode because you can't actually DO anything in the UI builder like that. Some actions you can perform through run like changing tabs, but what you are asking it to do is actually run game code which you can't do.

Turn off run.

What you need to do is simply hide and unhide the various sub windows you want to work on. Do this:

1) Go to the Tradeskills tab in the UIBuilder
2) Expand the tradeskill window
3) By default I think the CREATE window is visible, so left click on that in the expanded tree
4) At the bottom of the window just above the properties is an EYE icon. Click that to hide that subwindow.
5) In the tree you see things like Recipes, RecpieFilter, Prepare, Create -- those are all the sub windows you are looking for. Click the EYE on each on whichever you want to see to work on it.
