1.7.2 - Mouse Input Lag

When running in Direct3D on a Radeon card, there's a significant lag in processing mouse input - the cursor movement will lag a second or so behind the actual mouse movements, although it seems smooth when it does occur.

Switching to a hardware cursor, as described at , fixes the visual lag, but the processing lag is still there - mouse events are recieved a second or so late, and any object following the mouse by using getMousePosition will display the lag.

This doesn't seem to occur in OpenGL mode, or with 1.1.3.
