Funciont Keys broken in v3.1 build 1374

[dsp_418]

After today's update, function keys don't work anymore.

Strange.  I know some special keys broke, But I have not found that the F-keys does not work.
Have you done some special key-customizations ? or something ?
What setup do you use the default CommanderStyled setup.. or Explorer Styled setup ?
