It happens when I let my system set idle and lose connection to my company VPN. Problem is, it won't close then and requires elevated privs to task mgr kill it...

real annoying!

Re: Invalid access to memory - System::FillChar

I'm starting to return to development, and upgraded to the latest WinSCP.
This appears to be pretty much the same error that I saw in Feb-March.
Do you want logs, or would you like me to try a debug version of WinSCP?

I've sent you an up to date debug build.

P.S. This was the problem that occurs when I turn off networking overnight, while WinSCP is still running. I'd estimate the crash as 50% of the nights where I do this.

Running in Windows 10 virtual machine on ESXi 6.7. Using FortiClient 5.6.6 to connect to work network. Only change was enabling keep-alive (null packets at 120-300 second intervals, depending on server). Left WinSCP connections up and locked computer after ending shift. VPN connection dropped overnight, but do not know if memory error happened at same time. I believe I only had text files on remote systems open at the time.

I'm not sure if it helps, but I also have a Cisco AnyConnect VPN that gets disconnected every 12 hours or so. I think this also seems to happen more when the computer is put to sleep/hibernated, but because it's somewhat random, it's hard to tell when it actually happens. I'll see if I can figure out any other patterns.

thanks,
Mike

Invalid access to memory - System::FillChar

I'm not totally sure when this happened - I just got up this morning and went to my computer and found this error. The computer has probably been suspended a few times between now and the last time I was using WinSCP. This isn't the first time I've seen a similar error (granted, I never have noted the specifics or reported it), and I think most of the time it happens after prolonged periods where the computer has most likely gone to sleep or hibernated in between use of the program and receiving the error. Btw, I always have WinSCP open and very rarely do I close the program.

Invalid access to memory - System::FillChar

I'm not really complaining; seems to be a "bug" mainly in that there's an error message, in this situation. This message (or similar) pops up when my laptop wakes up from sleeping with the WinSCP window minimized, while working remotely via VPN to my office's Linux computer. The VPN link is gone and the program gets confused. It'd be best to simply report the lost link, and go away.

If the WinSCP window is open when the link drops, the UI's behavior is rather annoying: the reconnect/log-in pop-up steals the focus and won't back down until the link is back, with the only other option being exiting the program. A more graceful return to the opening screen would be nice. I do like that each connection remembers which directories it was in, once restored.

Overall it's a great work-horse utility, worry-free regarding data integrity, reliable, swift transfers, and intuitive UI.
