Subject: [PATCH] [0.4.13][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.
