i installed the constantine game today and its movement has problem.
i move the mouse but the game doesnt.sometimes its normal,and sometimes its not.the graphic doesnt have problem and the game speed is perfect.
why is that?

With an intermittant problem like that, it's either the mouse and or driver, or there is a bug in the game. This developer is Bits Studios (in the UK). Here's their website info:
