My OS - Windows XP Home
WinSCP version - 4.1.0 (build 375)

Thanks for your post. This issue has been added to tracker.
Workaround is to downgrade to 4.0.7 (if that does not help, please let me know) or to disable keepalives.

in 4.07 all is ok

Can you explain how/where one can disable the keepalive function?

Please read documentation. If that does not help, come back.
