Well, now I know it's not just me getting strange behavior. Maybe they're working on something. Some times, when we're working on stuff, hof goes a little nuts too.
I'm never sure whether I should post this, but is the server running slowly at the moment (and for the last ferw weeks/months)? I could put it down to being on the wrong side of the world, but I just had a quick look at The Kave's forum, and it ran a lot quicker. Clicking on the thread pane here takes a good ten seconds to load the thread, and loading the site into a new tab can take twice that long.
It goes through bouts of slowness for me. Some of them pretty pronounced. It was pretty much unusable the day before yesterday for example. I'm pretty sure it's the server rather than the software.
