I have 6.31.4 and I have DirectX 9.0c installed. This, however, doesn't answer my question. What's causing the system crash when I use F11 to bring up the debug panel for the frame rate? The engine runs fine, but, when I press F11, the system suddenly stops responding and control+alt+delete doesn't work so I have to use the reset button to restart my computer.
