If you are using an antivirus program, such as AVG ...it slows down this site drastically. There are options to disable avg for certain web pages, again it leaves you open for mischief but if you are a die hard solver you might want to look into other antivirus programs. Avira, Avast ...AVG uses huge amounts of your processors resources, its an excellent protector but it slows this site down enormously. Whether in IE8 or FF. You might want to look into trying Google Chrome. Its basic. No frills however it works well here.
