Argh. :(

Somehow, between whatever I have on my machine (the "good" one, the desktop that runs fast half the time and not at all the other half) and the recent changes to LJ, I wound up having links that didn't work unless double-clicked on. So I tried (in frustration and desperation) set opt_exclude_stats 1 -- and that cleared it up.

I'm in the sort of mood where I even resent video for existing on the internet, because of my whole computer situation.
