Isn't the best way of blanking the mouse to use SetPointer with
a transparent image on the active window, just for the sake of
compatibility? One day, the mouse-pointer may not be a sprite...

Roughly something like (pseudo-c ;)



void BlankMouse()  /* function called when blanking and staying blanked */
{
    struct Window *window;

    window=IntuitionBase->ActiveWindow; /* assume LockIBase()'d */

    if(window!=blankwin)
        {
        UnBlankMouse();

        blankwin=window;
        save=all.the.lot.of.values.stashed.in.blankwin.to.describe.the.pointer;
        SetPointer(blankwin,&zerochips[0],0,0,0,0,0,0);
        }
}

void UnBlankMouse() /* to clean up the mess */
{
    if(blankwin) return;

    if(CheckIfWindowReallyExistsByTraversingWindowList(blankwin))
        SetPointer(save);

    blankwin=0;
}




Am I right?
