No. It happens lately when I'm reading a page in the forums and I want to go back a page or two. I hit the page number, and the ad (various ads) pop up but the rest of the page doesn't load and my laptop says "done". I hit refresh a couple of times and usually it will load then. I tried a couple of computers, as well, and they all do it.
I've also noticed that when you're posting a response in the forums, it hasn't been timing out for me lately, which is a nice plus.
