Why does this happen?

For some reason, this game worked fine and now it glitches. In this drag-and-drop game, when you start names are shuffled and placed from an array on the bottom of the screen. For some reason, the top 2 names in the far right hand column can’t be picked up - you get a type cursor instead of a hand cursor. Anybody know how this happens?

Looks like the score (and time) text box is creeping down and overlaying those words getting in the way.

Yes!!! Thanks a lot!
