Spinning issues

Using Creo Parametric 8.0.4.0 - Spin Center is turned off so that it will spin about the mouse location.  Datum Plane shading is turned off (though it doesn't matter if it is off or on), and are not visible in my model.  When I hold the middle mouse button down, many times it won't activate the spin, and if I'm in a feature, often will close me out of the feature instead of activating spin.  When it does activate the spin, as I'm spinning, the spin location will jump to other geometry as the mouse cursor goes over it, instead of staying on the entity or location where I originally started the spin.  This only has happened since upgrading to 8.  I never had this issue with Creo 5.  Not sure if this is a graphic card issue, or an issue with Creo.  Running on a Lenovo P51 with an Nvidia Quadro M2200 card.  Incidentally, when I have Spin Center turned on, I still can't get the spin functionality to initiate many times when I hold the middle mouse button down.
