Remote editing doesn't work properly in 4.0.0 beta

I'm trying latest version available of winscp 4.0.0 beta

I really appreciate the new support of FTP protocol so I start to use winscp for FTP site management. But when I edit a file directly in remote (through FTP connection on a linux server) changes are often lost (9 times on 10) and - surprisingly - latest char of file is duplicated.

Hope this will help to fix the bug.

You may want to keep an eye on this thread.

thank you :D
