Well, I'm sure glad it's not my computer. I'm amazed that those of you who responded in this thread (Bansai, Flutefish, Kat, FerryM85, and Maradnu) are some of the fastest players among us and have experienced this lag.
I'm on a self-imposed exile from playing for the rest of this month (

Stephen, thanks for looking at the problem.
