Re: Cant save changes
I had the same problem which was the result of an inaccurate clock on the client machine. Specifically, if your local workstation clock is running slow and you have "Preserve Timestamps" enabled in the "Transfer" preferences, then whenever you edit a file, the timestamp of the modified file will still be less than the timestamp of the original file and therefore WinSCP doesn't even attempt to copy the modified file back to the remote server. If you correct the time on the local workstation, then everything should work fine.
Thanks Frank. That perfectly expains this problem. I'll modify it so that file gets uploaded whenever timestamp changes. Not only when it change to later time.
