I'm using polish version, so some text may be different.

1. Connect to FTP via right->connect ftp->user->password
2. Do something else for some time.
3. Try to go somewhere else in FTP tree

I get "can't change directory"
and I suppose to just change directory or to be able to copy files.

If I try recconect (1) I got error. When I try to close "active VFS" via command, nothing happens, FTP remains displayed there.

Only one helps - quit mc and start it again and do (1)

I've compiled this version, but also I used 4.8.16 form Slackware package and had same problem.
