I have noticed a slowdown with 5.13.2 on w1064 - 1709. Only 4 saved sessions. After logging in, the ui will not respond for 15 seconds or so. This just started occurring.
Slowdown comparing to what?
Can you send me an email, so I can send you back a debug version of WinSCP to track the problem? Please include link back to this topic in your email. Also note in this topic that you have sent the email. Thanks.
You will find my address (if you log in) in my forum profile.
