When your obs hive is closed up, how do the bees act?

[twb]

From recent posts you may have noticed we had a moisture on the glass issue.  My obs hive is closed up now for a bee talk and the glass is clear but the bees are going around and around the outside edges of the inside of the hive.  Is this normal?  It makes sense that the foragers know it's time to forage and are going nuts trying to get out, but do all obs hives do this?
