I've waited a bit to respond, as I was hoping that someone wiser would give you a direct and useful answer.

I can't. But perhaps someone could if you told us a bit more.

I assume your reference to "submit" is to the submit button on the page linked from "More Newest Nodes Settings" which is atop the Newest Nodes page (and which was added to that page in the past few months, IIRC). If so, I can't duplicate your problem. If not, please clarify.
