Microsoft explained: When users use the Win8.1 and server R2 platform to run some special desktop game process, the user's mouse clicks will be unresponsive or locked. This problem occurs because the Win8.1 changes the way mouse input is handled, so that the game is handled and manipulated differently from previous Windows systems.
