Lotta people complained that longer threads were getting very sluggish — clicking, typing, etc.

I tracked this down to the latest version of jQuery, which I installed a few days ago. I’ve reverted back to v1.3.2 while I try to see if it’s my problem or theirs.

It could be that as jQuery matures it’s adjusting its optimizations for average-sized web pages, and as a consequence doesn’t handle larger pages like long LGF threads as well.
