Thank you for giving this matter some attention.

Since I last used lftp I was issued a new laptop running Windows 10. 
Previously I was running Win7. Win10 has been giving me a number of 
access problems, which seem to be resolved by running Cygwin in admin-
istrator mode. This particular problem with 4.8.0 goes away in admin 
mode, which is now my standard operating mode, so 4.8.0 is no longer 
a problem for me.
