[Dx4win] Error 40 ??

[Mike Rhodes]

   ...trying to fix an old typo (4/24/15) where for whatever reason I 
have a Z instead of a 2 in a DX callsign (LAZXK). However, when I change 
and try to save, I get "An exception occurred! List index out of bounds 
(40)". Not even sure why DX4Win accepted it in the first place except 
that it looks like I possibly imported it from an ADIF file. The rest of 
the entry appears correct.
   Have shut down DX4Win and restarted but no help. Any clues?

Thanks,
Mike / W8DN
