To prevent undesirable release of analogue joystick while using touchpad.

While playing FPS game like Goldeneye, The World is not Enough etc with touchpad, the cursor/crosshair/crosswire tries to return to origin/centre thus preventing player to set it to target hence shoot it. Now this can be prevented by pressing Left Window Key, then moving cursor through touchpad.
