There is a bug in Unity 3!!

When Unity detects a bug in programming, catches some problems and totally fails

This problem has been in the Beta version too

I face this problem even in some others projects

Watch this video

From your video, I have no idea what your problem is. Is it the selection box? You have to completely surround an object to have it selected.

You have an error in the console that says it can't find the headbump animation so you might have named it wrong.

I see it... At about 1:00...

Submit the bug report....

If anyone wants...

See around 1:00-1:10, when he does the selection box, it doesn't start where he starts dragging. It starts off a little bit...

Does it going up and down...

Just look at the cursor when he drags, and the selection window...
