HidePointer -- hide the mouse pointer in the current display
Synopsis
HidePointer()
Function
This function hides the mouse pointer. Use this command with care because
it might confuse the user. You can bring the pointer back to the display
using ShowPointer().
Please note that every display has its private pointer setting. Thus,
this function will only hide the mouse pointer in the current display.
If the user activates another display, the mouse pointer will be visible
again.
