AutoCAD Inventor :: Nvidia K5000 Anti-Aliasing Mouse

I have an issue with anti-aliasing.I have had a K5000 for a couple of months now and tried various updated drivers but still have an issue with my Autodesk Inventor setup. I have now updated from 2013 to 2014 (Inventor) and still have the same issue.

I have Inventor set to Quality on hardware. The anti-aliasing then works ok. I can rotate the view using my 3Dconnexion mouse fine, and the anti-aliasing continues to work. But as soon as I move the mouse I loose the anti-aliasing. The mouse driver is standard windows. I have no other software installed on this windows 7 64 workstation, only Inventor and Excel.

I also have a laptop workstation using a Quadro FX 2700M. The anti-aliasing works fine on this machine.I have a mouse attached to laptop. It's the same brand but slightly different model to the workstation mouse (both Razer). I have both machines with the standard mouse driver, not the Razer driver.I use a 3Dconnexion SpacePilot Pro on both machines with the same driver (v3-16-1_r1342).

When I open a file in Inventor, and the mouse is either over the ribbon menu or the top title bar, I can rotate and zoom using the 3D mouse and the model is perfectly anti-aliased. If I move the mouse in the ribbon menu or top title bar the model in the workspace is still anti-aliased. But as soon as the mouse passes over the workspace or side Inventor explorer menu the model reverts to standard non-anti-aliased view - as if I had Inventor set on Performance rather than Quality.

Also, if the mouse is positioned over the workspace or explorer areas and I rotate the model, the anti-aliasing 'switches back on' so to speak. I can rotate and zoom again and the model is perfectly anti-aliased - even though the mouse is over the workspace or browser. But as soon as I move the mouse I the model reverts to non-anti-aliased again. Until I re-use the 3D mouse.

One thing I did notice, was that if I change the Inventor view settings to use an IBL environment then I do not get this problem. The anti-aliasing does remains even when I move the mouse. But unfortunately, this is not a perfect solution as it means every time I open a file (which is every few minutes) I need to re-apply the IBL setting, to which there is a time delay.

I am also getting artifacting/glitches in the Inventor IDW Drawing environment. Every horizontal inch up the screen I get a pixel shift, a sort of mis-alignment where the pixel 'row' of the screen has shifted horizontally by a pixel or two.I have contacted Nvidia who suggested using the Autodesk certified driver, currently 307.45, but this has not had any affect.
