Had not used WinSCP for over a day - it had just been sitting there. It crashed just as I connected to a different network from suspending the machine.

WinSCP 5.9.5

Error message:

The problem happens rarely. I cannot reproduce it.

This happened when I undocked with and active connection to an AIX 7.1 instance.
When I picked my laptop back up, it was there.
I shut the lid, but the laptop did not suspend or drop connections.
This is over VPN.

I just left WinSCP open for a while and got this. The app stayed up too. I didn't notice any ill effects, but it told me to report it and I always do what I'm told.

I know how to reproduce the problem or the problem happens frequently enough. I wish to be contacted by the WinSCP team to help resolving the problem.

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.

I have no clue. WinSCP worked fluently then I hibernate the laptop, awake it, put it into sleep and after reawakening this error appeared. For me it's not a big deal because I had to reboot anyway.
