If you find cases where tabbers are not working, but navboxes are, then that would really be worth further investigation because that really shouldn't happen. I've never noticed a connection, but I'll watch for that next time I see a problem; when I've seen a tabber issue, I usually reloaded the page before the navbox had scrolled into view. You mean you edit a page, save it and the script isn't working, but after a reload of the page it does? When I see a tabber issue, it's nearly always when clicking on a page in the activity feed--usually the current event's page, but sometimes past events when people are editing them too. Then again, event pages are where a tabber failure is most noticeable and also some of the most frequently edited, so that could be coincidence.

Regardless, on any page, the problem always clears with a reload or two.
