Hi, and thanks to Chris, Clive & Darrell for replying. Well I've reloaded N1MM and the problem has gone away - I'm kicking myself for not trying this first before posting. Clive, for info, the problem was with any F key, using ESM (which I prefer) and the problem was persistent. Finally, I would just like to add that while I've only posted a few times I've been a member of this reflector for a couple of years or so and read the posts daily. It's a great place to pick up tips. Thanks again.
