My Laptop is an Intel Corei3 processor, Windows 7 64 bit. I don't install any dodgy software on it and any other web-sites always load really quickly taking only a second to load.
Maybe I'll have to re-visit this problem again after trying Chapter 3 on some other PCs, after the web-site goes live.
It was just a problem when loading it for the first time into either IE, Google Chrome or Safari. After the first time, it took 1 second or less to load.
