The error was displayed on-screen after WinSCP was open all night on a laptop, which I do often. During the night I had issues with my firewall and DNS resolution stopped working, but there would have been access to the internet if connecting via IP. This is likely to happen again until I figure out how to fix the config issue on the firewall, so I'll try and replicate the issue by leaving WinSCP running nightly and see if it crashes again.

I've been using WinSCP for a few years now and have not run in to this issue before. It's a great piece of software, thanks!

I disconnected from VPN and i think this caused it, but i only saw the error 2 days after disconnecting (didn't check the laptop during that time so I don't know when it crashed exactly)

@hmeganat: 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.

<Try to describe precise steps that lead to the problem (where do you click, what keys do you press, what do you see, etc.)>
winscp had been running for days and my VPN connection had been reset.
I reconnected to the work computer and dragged and dropped the file from remote to local and received this error.
Then I refreshed the directory list on both local and remote and tried again and received the same error.
So I quit winscp and restarted it and then it worked fine.

(0000F12E) ntdll.dll.KiUserExceptionDispatcher
(004FCC47) Vcl::Imaging::Pngimage::TChunkIHDR::Assign

The problem happens rarely. I cannot reproduce it.

When I open the WinSCP site it stays only for a few seconds and then I receive an error report. I am unable to take a screen shot as there isn't enough time.
Thank you,
Rhonda

The problem happens rarely. I cannot reproduce it.

The remote node was connected by a crossover cable and was offline at the time. Therefore it may have taken the Ethernet link down prior to the crash.

My machine has been up for 18 days, and every night I put it to sleep. Today I resumed it from sleep, and notice this error dialog on my task bar.
I'm not sure how long its been there - maybe even more than one day. I do frequently fiddle with the network interfaces, so perhaps this triggered some kind of edge case.
