I have sent you an email with a debug version of WinSCP to address you have used to register on this forum.

Though only now I've noticed the version of WinSCP you are using. Please upgrade to 5.7. I believe it fixes your problem.

I had uploaded a file to the server and was trying to scroll through the list to see if it was there. Somehow I accidentally triggered a file transfer of a different file, and I cancelled/aborted the download. I again tried to scroll through the list and again accidentally started a file transfer from server->local, I'm not sure how (I was just using the arrow keys). I immediately started trying to hit the abort button but the PC was unresponsive. The dialog showed with the abort button, but the timer was stuck at 60 seconds. I waited a while, and it eventually started counting down, it went all the way to 52 but then jumped back up to 60 and got stuck again. At that point I clicked it, and got a few more dialog boxes telling me that I could abort. I kept clicking abort and eventually I got the crash report box.


I have "Enable session logging on level:"->Normal, but none of the other session options were checked. I've attached the contents of the log window, it doesn't look helpful but who knows.

BTW I was blocked from posting this because the forum software didn't like the function name "ExplorerActions__Execute" and I had to censor it by putting in the underscores.
