1. Compile and Run the attached example.
2. Create two internal frames using File:New Menu.
3. Type text in the text area of the selected IFrame.
4. Single click in the text area or title bar of the unselected frame.
   The IFrame appears to be selected however if more text is typed
   it goes to text area of the formerly selected Iframe.

In other words single click inside an unselected frame selects it but
the keyboard focus is not adjusted accordingly.
