SpacePilot + Dimensions = Jumping Text

The text of vertical dimensions in Perspective view constantly jumps and flickers when rotating the view with SpacePilot 3D mouse. Does not do this when rotated with standard mouse. Any reason why? Can anything be done to fix?

Hi Brian - I see the dimension location flips from side to side of the dimension line but this happens with a mouse as well as the 3dConnexion device we have here.
