ipv6 support not working under vista 64 bit (winscp 3.8.2)

Putty 0.58 and WinSCP 3.8.2 can't use ipv6 under Windows Vista 64 bit.
Putty 0.59 can use ipv6 under Windows Vista 64 bit.
All of the above versions can use ipv6 under Windows XP 32 bit.

Could you upgrade WinSCP to be based on newer version of putty code.

Added to TODO list :-)

This feature has been implemented already. It will be included into the next major release.
