View Control and other things missing

I've opened ORD (v10.09.00.91) today to find View Control now missing under right click and F9 now mapped to Key-Ins browser (previously plan/3D view).

No idea what's caused this but how can I reset/correct this back to what it was originally?

I've seen a post about this through customisation but this was a default setting so shouldn't need any new customisation?

Thanks,

Ken
