Currently we use a combination of D3D and Windows Forms to handle the mouse cursor. This can cause imbalances when switching between From and D3D Fullscreen.

The mouse cursor may be hidden or shown when not intended. This needs to be streamlined over an API that takes care of the states of the form and the D3D fullscreen without having to check at various places in the code.

In addition Win8 has a new state for no-mouse-cursor because the user is using a touch input method. This should also be taken into account and might have side effects on the current mouse positioning/click routines that are not aware of touch input.
