Thread:Project:Support desk/Publishing pop-up to be disabled

Good day!

Since Mediawiki 1.20 (or was it 1.21?) a new "pop-up" window appears every time one wishes to publish some changes to a page within a Mediawiki page. I have spent some time to find the extension/settings for this pop-up, but failed basically. Is there a way of disallowing the appearance of this pop-up, or any way fine-tuning it?

Thank you for your help!
