Can't close Media Manager Properties Pane
 

According to the Vegas Pro v8 manual page 83, Media Manager should have a stick pin to open and close the properties pane. My Media Manager does not have a stick pin. I can right click an item in the media list and choose "Show Properties Pane", which displays the properties pane. However, there is no way to close this pane once it is open.

I'm using Vegas Pro v8.0c.
