Walter, it sounds like you're the only person having a problem, and only from 1 machine.
I check the site regularly throughout the day from 3 different machines and don't have a problem.
Have you got some weird firewall/AV/Spyware/ISP/?? settings on your laptop. How are you connecting with your laptop. Are you running Onspeed (normally brilliant but it can occasionally cause problems).
I'm no computer expert but, from the lack of other complaints, your laptop does seem to be the exception rather than the rule.
