Not closing connections to FTP Server

[Reggie]

I am using Filezilla, latest release, and are seeing connections being left open to the server after I have clicked on disconnect.
The last command I do see coming across to the server is the LIST command, and that is were it is hanging.

The server is WS FTP 7, running SSL.

Below is an output of the log with debug on from Filezilla.

My system I am running Vista Ultimate X64. When using other clients the connections are closing out properly.

Nothing unusual with the log, according to it all connections get closed.
