You have to hide it first, otherwise, Windows just moves the caret
without changing the previous display.  The easiest way to avoid
this is to create your own function, a la:

void
MySetCaretPos(x,y)
int		x,y;			/* New caret position */
{
    HideCaret(NULL);			/* Hide the caret */
    SetCaretPos(x,y);			/* Move it to new position */
    ShowCaret(NULL);			/* Display it again */
}

This should work.  You may need to replace the NULL with the
handle of the active window (or with GetActiveWindow()), in
which case you'll have to add another parameter.
