From 896d4a4d5c9f9dc3831a23b81d39ff00e6f6d33f Mon Sep 17 00:00:00 2001 From: Richard Moe Gustavsen Date: Sat, 14 Nov 2009 10:59:35 +0100 Subject: Cocoa: native dialogs might hang the application on close This patch implements the same fix as 639b9c0286f0f2d5e50121df8d4125f029074510, but when someone spins the event dispatcher manually (calling processEvents themselves).
