+
+An mouse capture lost event is sent to a window that obtained mouse capture,
+which was subsequently loss due to "external" event, for example when a dialog
+box is shown or if another application captures the mouse.
+
+If this happens, this event is sent to all windows that are on capture stack
+(i.e. called CaptureMouse, but didn't call ReleaseMouse yet). The event is
+{\em not} sent if the capture changes because of a call to CaptureMouse or
+ReleaseMouse.
+
+This event is currently emitted under Windows only.
