What's odd is that when I run the lx menu editor it shows the Other cat as I would expect:

I would be totally happy if my Other looked like lxmed thinks it does.
I suspect this is what this guy was talking about, and possible the reason folks ask about removing the Other category altogether.
I tried an update-menus. I tried making changes in the editor above.
I tried doing the copy xdg menus to .config/menus and editing them there, per threads here and the xfce wiki on menu changing.
I tried removing the screensaver stanza from the /etc/xdg/menus/applications.menu since 99% of the entries in Other seem to be screensavers. Logged out and back in after each change.
I don't understand. It's time for me to stop the car and ask a local citizen for directions... thanks for reading.
