@leocg Obviously, of course!
Well, at least, it should be so in a thoroughly QA'd update process.
The issue here is that there is a difference, in this situation - the automatic update throws a warning and the downloaded update (according to other posters) does not.
My request "Can we request some one on the dev / QA team to see what the difference is between an autoupdated update and downloaded update" was for them to look into this specific case and not a request for general info on autoupdate vs downloaded update.
Thanks again to everyone in the Opera browser team for a good browser - just that this issue needs to be escalated for a QA team / dev team response.
