Howard:

I've used n3fjp's software for three years now.  Works very well.  As 
stated in another message, correction is the only hangup. You must click on 
the record you want to change, then click on edit.
Otherwise, very good software.
I use all his contesting software, and his general log as well.
You can get a cd with the whole shooting match for $49.  If you want to buy 
the field day by itself, its only $6.  Best deal around.
