Has anyone else noticed the lag time in loading the shout box?

It doesn't happen every time. But I leave my IE window open all day and when I come back and try to access one of the forums, the page stops responding for a good 10 seconds. It seems like it is trying to populate the shout box. And it only does this once. After the lag, the page comes up just fine and I don't notice it again until I step away from my computer for a bit and come back to the site.

I checked the generation stats below and all the times displayed well under a second.
