    Hi Ian,

    had the same problem some time ago......take a good fitting srewdriver for the srews head, lay the driver face down on a hard surface, a good punsh with a hammer on the srewdrivers back, in most cases it works now.

    only my experiance, maybe it will work also with your driver.

    OLD TRICK

    Try to tighten it first an then it should come free easily. Make sure your screwdriver is the correct type for the screw. This tip works a treat for old woodscrews esp brass like you get on door hinges but also works on machine screws.
