Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.
We've had a problem for some time now using WinSCP (5.96 GUI on Windows). I'm able to log in and transfer files just fine, but when I navigate my local directories the app periodically hangs for at least 3 minutes before refreshing the contents. For example, I'll click on a local subdirectory and it will hang for 3+ min before displaying the contents. My guess is this is not a WinSCP issue as it doesn't appear to be happening to others, but it is happening to my coworkers so I suspect it may not be playing nicely with some other piece of software. Are there any logs or logging options we could use with the tool to figure out where it's hanging and/or why it's hanging? It's close to useless at this point.
