first of all, thanks for this great program. I've been using it for years.
There's a problem that I can't reproduce reliably, but it has been occurring for a long time, with different computers, Windows versions and WinSCP versions.
The "Keep remote directory up to date" mode sometimes doesn't notice when I change a file. I use that mode to develop websites. I have a local copy of all HTML files etc. that I work on, and WinSCP copies my changed files to my webserver.
I think it mostly happens when I copy a whole batch of changed files, as if WinSCP didn't react quickly enough.
Does anyone else know this problem and maybe how to solve it?
