[NA-User] Interface problem

I have always noticed this with my 1000mp but always figured the program was
designed to run WITH the radio on. I do as was mentioned and just restart
NA using my BAT file that I always prepare for each contest. It happens so
rarely that it's not a big deal but something for Dave to work on in his
'spare time' !!
Hope ten opens somewhere this weekend!
