Hi Astrobob,
Thanks for the reply , I unplugged everything and the fault was only happening when the iPac was plugged in.
Decrease volume was assigned to ‘D’ this is also mapped as a button, but when testing in notepad it only appears when I click the button .
I have removed the assignment in bigbox and the problem has gone .
Still strange in only happened on first load in a windows boot .
Thanks
J
