Hello,
I wanted to make a copy of my query by choosing File->Saves As->Save Object As->Query
The new query is being opened in a new tab but it's not included in object list. Choosing Design Mode or Save as generates the following error
Having said that, choosing copy+paste in object menu creates a copy without a hiccup. I'm not sure if there's any difference in practise between these 2 methods, I was just following tutorial :-)
