Fix Window CLOSED event when using more than one window

Browse Source 
Fixed an issue where if there were more than one window, when they were
closed, the CLOSED event would trigger but the window count did not
decrease. This happened because after the window was destroyed the
DestroyNotify event was triggered, which when looked up in the m_windows
map, reinserted itself with default initialization.
