^ That, and did you change the update interval to something less? Maybe 1 hour or 3 hours?
Mine will lag sometimes when driving home, but I always assumed that if I have it update per hour, that it wouldn't notice the change in the location until it performs an update? Now I'm not so sure. The lag in changing the city doesn't bother me much. What bothers me is when its dark out and it says its 73 and sunny! lol
