There's a number of options you can play around with in this view by going to Preferences>Layout (1)>Main Panel>Configure Views>Artwork. From a brief glance at them, you may be able to disable that menu being shown. However, before you do that, I'd recommend updating to the latest beta (from
here) as that gives you a whole range of new options there, some of which you may prefer.
