\me slaps head HARD. 

This is the obvious solution. I spend all my time dealing with networks
and forget the days when floppies and the like were used for moving
stuff!

I'll try it as soon as I have time. I suspect that at least the will get

I'll be looking for another card soon. :-(

Thanks for kicking my brain over to the right track!
