Default [Q] Resurrection Remix Halo Question

So I'm currently running Resurrection_Remix_KK_v5.0.7 and the standalone Halo app doesn't work for me. I can pin apps to it, but I can't open them in the little floaty window over another app like I used to. Am I doing something wrong or does this not work with this ROM any more? I should note, Halo notifications work fine.
