From 3d560a498803fadfec9163d7a9695aee60cca8d4 Mon Sep 17 00:00:00 2001 From: Joerg Bornemann Date: Mon, 25 May 2009 16:26:13 +0200 Subject: BT: fix systray balloon crash bug on Windows CE Its the context menu handling code... again. Problem is, that during execution of translateMouseEvent, the widget is closed and a modal message box is shown. After that, there's no widget at globalPos and thus, alienWidget is null. This patch just adds a null check for alienWidget.
