i was alt tabbing around, took a screenshot, sent it in slack, back to winscp, tried to move from a/b/c to a/b/d using the right side, and got an error, then it asked me to reconnect. I was connecting through a vpn if that makes a difference. Probably a weird edge case, alt tab is definitely involved.

Idk where to find the session log sorry

Clicked on open WinSCP window that I know had gone inactive (computer went to Sleep in meantime.) But since WinSCP screen was still open and displaying the right pane as I had left it connected some hours ago, I left-clicked in the right pane window expecting to be presented with either question if I wanted to log into this same server or to be presented with the Site Manager to select a site. (trying to remember if I left-clicked on the right pane's top window with the folders, or in the bottom windows showing the file contents of that highlighted folder. Reasonably sure that it was the right pane's Top Window with intention to go to another Folder (in case WinSCP still had an active connection to that displayed ftp server)
