I'm not sure why but when I hover over geometry, edges, planes is does not highlight. Also when I first create a new sketch the planes do not show up, so I can't pick the top, front or right view in the display area. I have to over to the design tree and pick it from there. Thats not a big deal, but when hovering over edges it doesn't highlight it and makes it more time consuming cause sometimes I end up picking the face and then have to deselect.

I thought it might be graphics card issue, its a NVIDIA GeForce GTX 560 Ti
