[fixed] WinSCP 4.2.x shows one more "empty" log-in prompt

Log-in process in 4.1.x:
- activate stored session (no password saved)
- server prompt appears (Password:)
- write password and hit Enter key to submit
- done, I'm logged in

Log-in process in 4.2.x:
- activate stored session (no password saved)
- server prompt appears (Password:)
- write password and hit Enter key to submit
- one more server prompt appears, no question, no prompt, just three buttons (OK, Cancel, Help)
- hit Enter key [OK button] to continue
- done, I'm logged in

Tested versions:
- 4.1.8: OK
- 4.1.9: OK
- 4.2.0 beta: bug

Seems to be same as https://winscp.net/forum/viewtopic.php?t=6620 (I've searched through old bug records but have to miss it.)

If I understand https://winscp.net/tracker/388 correctly, it's already fixed.

I'll wait for version 4.2.3.
