undo 'dock as tabbed document'

Yesterday I right clicked on the Connection Manager window that was located on the left hand side of my screen and selected ‘dock as tabbed document’. The Connection Manager window then changed to a tab rather than a window on the left side. I liked it better as a window on the left side of the screen and would like to change it back to that configuration. However, nothing happens when the Connection Manager tab is right clicked. I was expecting it to give options to change the arrangement but it does not. I looked through Tools > Options and did not find anything that could change it back to the way it was before this change. The version is Toad 6.7.0.176.
