this is a weird bug, I have only since the WinSCP version 5.5.2
I am on Windows XP (SP3, 32).
I use normally the multitabbed Editor EditPad Pro, version 7.3.1
Often I edit files from my SSH-connected Ubuntu Server with SFTP in this editor.
But sometimes, it happend now the second time, I wonder why the changes are not visible, but I did save them, no error message.
Reason is, that WinSCP doesn't upload it again.
So I tried with a single window editor, TedNPad, but still the same.
It will work again, I thought, when I restart WinSCP, but this is a bit annoying, because I have three WinSCP tabs and files open.
But no, this doesn't still not work, when restarted WinSCP.
I tried to upload big changes, so WinSCP should be busy a little and I can look into the Queue, there I see strange Progress completed and Transferred 0 B, after a short while Queue closed:
I dont remember to have this bug on previous WinSCP versions. Could it be related to the previous bug ("fixed") with Copying files from remote side failed?
I don't think it is possible to log WinSCP, because this bug appears not often, so the logfile could be gigabytes.
