Yeah, turns out there are many issues, only on Chrome, and it appears to be mostly with non-ajax page elements, so I think that's why I'm seeing it only here on WP, with phpBB2, where most of the page elements are not using ajax. It probably will do this weird stuff on some other sites, but I haven't seen anything yet.
Nothing is consistently wrong either. Different things on two different computers. Edit buttons not working on pages, searches coming up empty, pages loading multiple times causing apparent back button malfunction, all Chrome only. They must have just initiated a bad update. Love the fact that they don't include a rollback function or publish their update versions anywhere obvious.
Anyway, it doesn't appear to be a WP problem at all. I thought it might be due to recent updates on the site, but seems that is not the case.
I'm going to change the topic title to reflect this.

As before when I first signed up here years ago, I'm finding that after a long hiatus, and after only a few days back on here, I'm spending way too much time here again already. So I'm requesting my account be locked, banned or whatever. It's just time. Until then, well, I dunno...
