Are you sure you actually have set the option is display new post indicator in admin settings?
Indicate new posts is set to yes in admin. I'm going to compare code between classifieds and gallery to see if I can find what's different. I know you maintain it works on your install but I've now installed both a stand alone and integrated version of 4.2 and now a fresh install of 4.21 and have yet to have it work so it's not because of mods or other edits to the files. I'm willing to bet it's something very minor but enough to make the difference. No worries... beyond compare is my friend.
