Is there a way to change the Finish button default on a VWF run from a custom button URL that's not referencing a VFP?  Basically I have a simple flow that starts with a button click from a detail page, which opens a new browser window and shows some data along with the standard VWF Finish button. 

What I'd like is for finish to close the window, not restart the workflow.

On the design canvas, I have 4 dropdown choice elements that do not show as required (e.g., no Red bar next to them, nor have I check any Required box in their definition).

But when the flow is run, all dropdown choice fields become required, with both a read bar to the left of the field and a clearly enforced required validation complaint if one tries to pretend they are options.

Any idea how I can avoid having all dropdown choice field being required?  I'm clearly missing something basic :smileyfrustrated:

Does anyone know how you reference the value that a user enters into the text box that displays when a choice with "Show Input on Selection" selected is selected by the user?
