I got tired of how slow my browser was loading pages on the SDMB and decided that doubleclick’s ads might be the reason. I blocked it using OpenDNS which I now use as my DNS. Things seem somewhat better, but now by “back” button does not work in SDMB. Any ideas why? It works on at least some other sites.
