changing language => hostname overwriten

Changing language in WinSCP 4.2.4 overwrites hostname, username and lot's of other settings.

To reproduce:
Download 4.2.4 standalone and finnish translation.
Start winscp
Write "example.org" into "Host name"
Click on "Languages" and change to Finnish
=>
Host name: HostNameEdit
User name: UserNameEdit
Password: ************
Private key file: PrivateKeyEdit
....all other text edit boxes behave similarily

If you type anything to the boxes and change language to English you get the same problem.
OS: xp/vista/win7
