I'm entering this from my work computer.
Is there something up with my internet settings? I used TCP optimiser the other day and everything seemed fine afterwards.
This happens using Safari, Chrome and IE 8, so I'm thinking it's a configuration in my Windows Firewall or something similar, rather than browser related.
Firewall is set at medium.
