Hi, 

I'm using NetAdvantage for Winform 12.1 for .NET 4, and now I'm working with UltraToolbarManager.

Our team designed our application to handle all handled exception at AppDomain.UnhandledException Handler, to deal with error log at one location.

So use Application.SetUnhandledExceptionMode and handle all exceptions like following code;

AppDomain.CurrentDomain.UnhandledException += (sender, args) =>
    {
        var ex = args.ExceptionObject as Exception;
 
        MessageBox.Show("Nice Catch in Unhandled Exception!\n" + ex.Message);
                    
    };
 
Application.SetUnhandledExceptionMode(UnhandledExceptionMode.ThrowException);

Everything goes fine, except UltraToolbarManager...

When click menus, it's OK. Unhandled Exception occurs.However, if I click toolbar button, ThreadException occurs and ,that's all. No UnhandledException fired.

Is it design ? Are there any ways to change this behavior ?
