OK, I'll have a play with that.

Yep :) Well, maybe. The down key works in every other app I use, but I've
had problems with this keyboard in strange ways before, so I wouldn't put
it past it. I'll try it out on another machine when I get a chance and see
how it goes. It's a laptop, so I can't really change the keyboard. (hmm,
maybe a usb external one, if I had one)

OK well I'll play around with this some more and I'll get back to you once
I have what I think is a complete, working patch.
