I know this has been disscused before but I did not find a answer yet. I just got a new computer with a Quardo 4000 grafics card and windows 7 64 bit with CAD 2011. For some reason now my crosshairs blink a ton when I move my mouse and it is driving me crazy!! Did anybody find a answer to this? I even had NIVIDA who make the card go through and set up my driver for CAD to no avail.
