Oui, that is the action of the tool, maxxxmodelz.  I was in complaint of this limit in early versions of the software also.  The late versions automatically exit the box-select tool after you make selection, which I find better than before.  Early versions forced you to use hotkey again to exit, so you were in constant hotkey toggling to move the view and make more select.

I would like to rotate view and not have to activate tool again, but the late improvement is better, and faster, than in early versions, so I can not complain more.  You will soon find this a fast method, but not as fast as you wish I think.
