Disappearing Properties Panel

Hi, everyone!

I am brand new to Blender, and I am working on a compositing and matchmoving tutorial. I have added some motion trackers to a video clip, added a small plane that I want to add particles to. However, the window on the right side of the interface that contains object properties and materials has vanished, and I cannot get it to reappear. I am pretty sure I did something to make it go away, and cannot for the life of me get it back. Can anyone help? I have attached a screenshot. I am running a new iMac, OS 10.8.2 with 32 GB of RAM. I also am using the latest version of Blender, 2.66.



Split the window and select the properties Window or change the Properties window at the top of your screen back to an Info window and select another screen layout
