I am using a logitech stx communicate webcam with my girlfriend who has the same the webcam over msn messenger. We are using the video conversation feature and recently it has been so laggy that it has been unusable. We both are on a broadband connection and I can't figure out what is wrong. The only thing I could think of is that she is on a network at her college and I was wondering if that is slowing it down. I also do this with my dad and we don't have any problems at all. Thanks.
