I was never able to duplicate Bryan's problem but it must have something to do with some setting or software. Such as what web browser,virus software ,firewall or operating system used.
Have you updated or added any software lately. Or have you changed any settings?
Or it could be a server problem that happens at the time you are visiting the site. When do you typically go online?
