Everything you said is correct.  I just tested it..  It fails with FuTTY, and 
works with PuTTYTray.   BUT, this bug also applies to the official PuTTY 
development snapshot.. So you should file the bug report with them so they can 
fix it.

Yeah, it looks like the PAGEANT key authentication regression was introduced 
between the FuTTY 2010-12-20 build (works) and FuTTY 2011-02-12 (failed).

I will see about reporting the issue on the official site.

FYI, I've been trying the daily drops of the official PuTTY and today's 
snapshot, SSH-2.0-PuTTY_Snapshot_2011_04_21:r9149, fixes this issue.

Well, I updated FuTTY to PuTTY 04-22 (r9149) just now..  but it still doesn't 
work for me.  Neither the new PuTTY or FuTTY works with pageant for me..  So 
recheck yours to make sure it's really fixed please.

Okay, so here's the deal. After you said the 2011-04-21:r9149 build of PuTTY 
didn't work for you I loaded the keys into PAGEANT and retried it again; and it 
worked, on my WinXPSP3 Home Edition netbook.

I then tried both you last two FuTTY (2011-04-22:r45 & 2011-02-24:r41) releases 
on the WinXP_SP3 netbook and they too where able to authenticated via PAGEANT 
keys. 

So then I tried the last two FuTTY releases and PuTTY (2011-04-21:r9149) on my 
Win7SP1 desktop, FAIL! None of them could authenticate via PAGEANT keys.

So, something is amiss with PAGEANT key authentication on Win7 (don't have 
access to a Vista OS to try).

This problem was introduced in Putty revision 9043:

http://svn.tartarus.org/sgt?view=rev&revision=9043

I just bisected the problem with Git... I can reproduce it on Windows 7 Pro 
64bit, compiling on Cygwin 1.7.5. Revisions earlier than 9043 are all OK.

Good work finding it!  But I'm going to wait for the fix from upstream rather 
than just revert those changes..  I'll revert it in a few months though, if 
they never fix it.

Yes, great work finding the problem in the code. I see the WinSCP project also 
encountered this issue (http://winscp.net/tracker/show_bug.cgi?id=662).

According to yesterdays changelogs in PuTTY, they fixed the Pageant issues.
I've updated FuTTY with the latest PuTTY changes..  FuTTY-2011-06-10.exe

Verified the fix on Win7SP1-64bit. Note however that you must use the current 
beta build (v0.60.9178) of PAGEANT.exe; the official 0.60 release version of 
PAGEANT.exe doesn't work with the fixed Futty/PuTTY (v0.60.9178).
