I don't think there is a task manager in this build, aside from the built-in WM one that you can see when you press and hold the OK button.
That top bar is more of a notification and settings tab, than a task manager I believe.
I think we'll need to install a free task manager program (like Quick Menu or something like that) to get an app to close when pressing OK.

Also, I think Voice Command was not included in this ROM. Can be added via cab, though.
