Technical Problem?

Sweet readers,

A few kind folks have brought a readability issue to my attention. It seems that sometimes, a sidebar ad appears, expands, and doesn't contract, obscuring the content in the center column.

Is this happening to a lot of people? I use Safari and Firefox, and have never seen it. Maybe it's happening to computers with Explorer?

Just wondering, so we can pinpoint the problem area.

Thanks!
Kris
