FCS6 - Mistake - Changed Interface

Hi Gang

I was editing/working with FC6 as I always do and mistakingly pushed a key or button which clearly changed the appearance of the clips on the timeline, Please refer to the links I provided.

Was wondering how I can get the clips back to appear (as they used to), in Picture2? Picture1 will show what happened when I inadvertently changed the display layout of the clips. I'm sure its something easy, (perhaps an option I inadvertently choose and should be able to be fixed by an adjustment or unchecking something from the Task Bar?

Here's the links with screenshots:
