So how come 3.2 works fine with my existing plink on XP? Sorry, not
trying to be difficult, I just need to be able to clarify (to my
management) why we only see this on Vista and what it will take to fix it.

OK. I wasn't trying to dispute the possibility of a bug in plink/putty...
I was just looking for a more detailed explanation. Thanks for providing
it. But I still would like to see a reason for why 3.2 works on XP if you
know.

Unfortunately, since the GSSAPI patch I have is for 0.58, I'll need to do
quite a bit of work to get it into 0.60 (the latest version of PuTTY).
Since this problem only seems to occur with KfW 3.2.2, I need to weight
the advantages of upgrading to 3.2.2 vs the time it will take to adapt my
patch to PuTTY 0.60 and test.
