Put the Continuum application on your desktop, right click it, and select "Show Package Contents" Click drive_c > Program Files > Continuum > banners> Find any banner you wish here and download the .jpg file Drag the .jpg into the "banners" folder above Open Continuum, enter a zone, and set your new banner using "Esc+b" This happens to me also, but more severely. Say if I decide to play Windowed, turn up what limited graphics Continuum offers, or run to many programs at once, Continuum will freeze, but unlike what you say, I can't "command+q" to restart it. I need to restart my mac which I feel is slowing killing it. I also noticed it does that the first few times you open Continuum. After playing on the portered version for mac now for about 4-6 months, it rarely freezes. Time should fix your issue.
