[NTUSER] Fix regression CORE-11828

Fixes symptom "mouse pointer vanishes when closing
    applications via x in title-bar"

The bug in WIN32SS was unhidden by SVN r65496 == git
    5c1a8109c84ed0aefdac2488ff666070a7ae52f6
    , when we introduced explorer_new. The old explorer
    had a workaround built within.

Many thanks to patches author James Tabor.
    I intend to backport into 0.4.13RC as well.
