But this is really only a minor point.
1.) Check for updates and make the user aware of them - if any.
2.) Let him chose what to copy to the SQL editor.
3.) Update the object browser while being at it - depending on OR regardless of his pick.
I would go with the user's choice. After a refresh, old information is gone.
If it is substantially easier to refresh objects in question right away, then I can live with that, too. As long as the user can get the old version
in the SQL editor.
