This happens periodically with my Outlook Express as well. It's not the browser because it's sporadic. Right now I'm dealing with not being able to send email. Some server problem "too many connections. Try again later." This is a problem with Fairpoint that I haven't had before. I'm able to send off and on. This caused a real problem last week as I was having a new boiler put in and couldn't reach the supervisor by phone to coordinate the work. I wish I had another choice for DSL.
