Also: "Error Listing Directory". I am on the latest version 5.1.3. I have seen this error posted several times here on support, going back a couple of years. I believe it is related to port blocking, since FTP randomly selects a port - So some networks are blocking certain ports. I have seen other clients that have fixed this problem. Is there an ETA for resolution? I love your product, except for this bug. Thanks

To be honest I'm not sure what I can do about this. Any suggestion?
