Download Completed Successfully

The problem: On download of a huge website, SmartFTP completes successfully although the download actually stopped on a large folder and the download must be restarted at that point to get the remainder of the files.

Frequency: I have had this problem in about 10 or more cases. On download of a large website with many files. Usually stops in an image folder where there are lots of files.

No errror message occurs.
Thanks, Joel
