Problems whith SSL

The SmartFTP client v2.0.997 seems have problems with transfer over SSL (both implicit and explicit).

When I download or upload files (>1.0 GB), the SmartFTP client performs strangely. The transfer becomes very slow or even idle, and sometimes stopped abnormally even there is no other connections from other machines to the server.

When I change it back to pure ftp/21 (w/o SSL) by editing the properties of the entry in the queue, the transfer performs very well.

Any body has suggestions?!

Thanks in advance!

Do you see any increase in SmartFTP's memory usage over time?

The problem seems about the SSL Data Connection.

When I changed the File Transfer to clear in the Favorites > (Ftp_shortcut) > Connection > SSL > Data Connection Mode > File Transfer, the Smart FTP works fine.

Buit if so. Is it still a secure transmission?
