So if an old info *.html gets Stuck with the corresponding node, Press Alt+New on the nodeeditor screen to clear the old info .html file.

This must be some kind of correctable bug in the info code in a node?
Closing a node should sever its tye to its info *.node?

Is there a superior way to code the info files than with .html?
