Hi! The latest build connection always leads to the message like `instruction at address `0xXXX' read memory ataddress `0xYYY' and memory can not be read'. The build 0.76.3.2 works fine w/ the same hosts

Hi,

i have the same issues, currently only when connecting to VMware Photon 1.0 VMs using login/pass. My Ubuntu Machine with Key works fine.

Leo - Sat 24/12/2016 14:52:02 CET +0100

Try to disable password save feature:
[KiTTY]
userpasssshnosave=yes

Fernando - Sat 24/12/2016 15:45:46 CET +0100

Same here. Password+OTP login too. The userpasssshnosave=yes change didn't seem to help it. Still crashes.

Fernando - Sat 24/12/2016 15:51:45 CET +0100

And I can also confirm that the previous build 0.67.3.2 works just fine with and without changes in the settings.

Oleg - Mon 26/12/2016 07:54:23 CET +0100

I've tried to set `userpasssshnosave=yes' before posting: it's completely in vain

Cyd - Wed 28/12/2016 19:31:30 CET +0100

Can you test the next beta build:
http://www.9bis.net/kitty/data/beta/kitty.exe

Alex - Thu 29/12/2016 11:34:58 CET +0100

The new beta proposed by Cyd works OK for me. Hope this change will be included into the regular compiled binaries as soon as possible. Thanks for the hard work!

Oleg - Fri 30/12/2016 14:36:59 CET +0100

I've renamed it to kitty_portable.exe, run it... and it works fine! Thank you a lot! For your time & effort, and, as a result - for an outstanding, perfect ssh-client. Wish you good luck next year and happy holidays!

Version 67.3.4 looks good. Thank you. :)

Warren - Tue 03/01/2017 18:38:29 CET +0100

Using the beta build and userpasssshnosave=yes but I'm still receiving "The instruction at 0x771443df referenced memory at 0x632e6873. The memory could not be read."
