I have a class of SFTP server that allows only one connection

[msfento]

and need to know whether there is a switch to set to have FileZilla reuse the connection after producing a directory listing.
What I'm seeing is I can connect to the server just fine, but after I get the directory listing, when I try to download a file, FileZilla initiates a new connection to the SFTP server, which promptly denies the connection attempt with an error -- already connected.
What I need is a switch setting (for this class of server only) that will allow for reusing the existing connection, rather than creating a new one each time a file is requested.

Thoughts?

The proper solution is to slap the server administrator with a trout.

As workaround you can limit the number of connections to 1 in the Site Manager.
