Lost cockpit mouse click

[unclebob]

I don't know what I've done but I lost my cockpit mouse click.
I have CEM and all other realism settings enable, mouse still works on game menus and pan view but it doesn't click anything.
Its not F9 or F10 option because I can toggle betwen them and when I put my cursor over a cockpit switch it changes from an arrow to a hand with label under it whitch means I'm in correct option.

I've notice that when I want to change controls assignments, mouse isn't recognize aswell. It seems that game doesn't recognize it as a valid imput control.
Everything was ok untill yesterday.

Anyone can help?
Thanks
