  • $\begingroup$ Not a proper place? Interesting. Because it says on the Orange website to ask Orange GUI-related questions on DS.SE. What other discussion forum or mailing list is more appropriate for this kind of questions? $\endgroup$

  • $\begingroup$ I guess it depends what you mean by 'GUI-related questions'. I interpret it as workflow construction. Do you interpret it as bugs and issues? $\endgroup$

  • $\begingroup$ Is what Dilip Bobby is asking about above a bug? Where do all other questions belong or, IOW, how does one properly reach the community? $\endgroup$
