Sorry rern, but I am not clear about the situation.
My version (20171128) of addons menu works perfectly well so long as I do not update the enhancements addon. Should I now be able to update enhancements without problems, or is the spinner problem due to something which is not corrected by the automatic addons update?
Addons was updated when I clicked the menu today so I tried updating the enhancements. This resulted in the spinning symbols again, so I reverted to the previous working image. I am not sure whether you are saying the uninstall/reinstall of addons is needed even if if Rune is working, or just for those stuck with a non-working installation.
