+Summary: Properties on NotifyIcon are ordering sensitive
+
+If the Visible property is set before the Icon property is set then the
+icon is _not_ drawn in the system tray.
+
+Mono 1.2.4 (installer). Tested only on Windows XP SP2, where it always
+occurs.
+
+Code like the following works and the icon appears in the system tray.
+ m_notifyIcon = new NotifyIcon();
+ m_notifyIcon.Text = "notifyIcon1";
+ m_notifyIcon.Icon = ico;
+ m_notifyIcon.Visible = true;
+
+However with code like the following where one sets Visible before
+setting the Icon property then the icon is not displayed.
+ m_notifyIcon = new NotifyIcon();
+ m_notifyIcon.Text = "notifyIcon1";
+ m_notifyIcon.Visible = true;
+ m_notifyIcon.Icon = ico;
+
+See bug 81667--"Crash from NotifyIcon.HideSystray on Form exit if not
+fully configured", where repro code is attached. Call the application
+there with a path to an icon filename on the command-line. As it stands
+the icon is not displayed. Move the "m_notifyIcon.Visible = true;" to
+the end and the icon does then appears.
+
+Either ordering works on MSFT CLR v2.
+
+
+In is not valid for the user have to know what ordering of properties is
+required. See the Framework Design Guidelines e.g at
+http://msdn2.microsoft.com/en-us/library/ms229006(VS.80).aspx:
+ DO allow properties to be set in any order even if this results in a
+temporary invalid object state.
