commit 234485511ff360c4ff95b87b2d0202c571af9675
Author: Peter Clifton <pcjc2@xxxxxxxxx>
Commit: Peter Clifton <pcjc2@xxxxxxxxx>

    hid/lesstif: Fix dropped crosshair artaefacts when dragging objects.
    
    It seems that the idle_proc redraw code assumed the crosshair was
    switched off upon entry, proceeding to redraw everything (and
    obliterate the crosshair in the process). The final show_crosshair (1)
    call only has any effect if the crosshair was notionally off before
    hand.
    
    As a quick work-around (you could probably do it with less flicker with
    a little more logic), ensure the crosshair is turned off just prior to
    redrawing the screen - so it will switch back on correctly afterwards.
