Occasionally for me over the last 2 days (and happening to me right now), I'll be sailing along just fine during a session and then I click on a link and it just seems to stall for about 45-60 seconds. Even if I click on other links. It's like Run 4 min/Stall 1 min/Run 4 min/Stall 1 min, on and on. Very erratic.
