My mouse on my Surface Pro 2 is acting erratic. I looked in your data base and could not find a solution. The mouse pointer disappears when it is moved and some times just blinks. I have tried different ports and mice with the same results. This just started happening yesterday. I have a UD-3000.
This is a regression from the 7.5M1 DispalyLink drivers and has been resolved in the 7.5M2 drivers that released today.
