I've been having some issues with the pages taking a while to load and not just the 1,000+ comment posts. Also my Z button is hit and miss - sometimes it works sometimes it doesn't and I'm on Internet Explorer. We were discussing this yesterday but that fanpost is gone for whatever reason so this is a new one.
I emailed SBN and they've responded wanting to know the details but I don't want to speak for everyone here. I know some have had some problems and some have none. So put in this post if you've had any problems, what those problems are (if any) and what browser you're using and I'll link this post to the guy at SBN when I email him back.
