Error reading ImageList192.PngImages: The parameter is incorrect - System::FillChar

2025-09-15 18:11

In WinSCP, I reconnected my session, then tried to open a log file that I had previously viewed a few days ago. I got the error message below, so I refreshed the directory and tried opening the file again.
See attached screenshot.
I tried opening some of the other files and got the same error.
By the way, I have some windows updates that are staged waiting for me to reboot. I will try that, but will lose this internet session when I do it. If I can get back to this posting I will let you know the outcome.

Error reading SessionImageList120.PngImages: The parameter is incorrect - System::FillChar

2025-03-24 03:00

- When i let the tunnel connection idle for three days and let it disconnect, and then create a new tab on WinSCP, this error pops up preventing me to create the new tab. Already open tabs can reconnect as usual. Happens rarely.

I made some file transfer, then left connection open but idle in background.
Connection was via a SSH port-forward using SOCKS proxy.
Later the SOCKS proxy closed unexpectedly, so the connection was lost.
When I return to computer 6-7 hours later the error message was popup on the screen.
