@seekerOfKnowledge: Disabling IsTabStop on the LostFocus is a good approach, but your re-focus hack is unnecessary. It fails to have any visible effect the first time around because the change of IsTabStop has not yet taken effect. This approach can be also be taken with any other control.

        var control = sender as Control;
        if (control != null)
        {
            control.MouseLeftButtonDown += (sender, args) =>
                {   //This event fires even if the control isn't allowed focus. 
                    //As long as the control is visible, it's typically hit-testable.
                    if (!control.IsTabStop)
                    {
                        control.IsTabStop = true;
                        //threading required so IsTabStop change can take effect before assigning focus
                        control.Dispatcher.BeginInvoke(() =>
                            {
                                control.Focus();
                            });
                    }
                };

            control.LostFocus += (sender, args) =>
                {   //Remove IsTabStop once the user exits the control
                    control.IsTabStop = false;
                };
        }
