[Halo]

I was looking at the toolbar section of the preferences and noticed that I could add items to a menubar. I added the "Add books" action to the Current Actions columns for the menubar, but when I restart calibre, I do not see the menubar. Well, to be specific, I see the menubar with my "Add books" item for about one second when the calibre window opens, but before calibre finishes drawing the user interface in the window. Once the window is done updating, the menubar disappears.

Is there a setting to tell calibre to display the menubar?

Using calibre 0.9.39 on Windows 7.
