Love WinSCP, been using it for a couple of months. Just noticed recently that despite the option 'update subdirectories' being left unchecked, it is repeatedly uploading subdirectories to the server.
This doesn't happen when I first activate the keep remote dir option (it only uploads files changed in the base directory selected), but the first time a file changes it then starts uploading all subdirectories. I sometimes find if I check and uncheck update subdirectories it'll stop doing it, but it does seem to be doing it most of the time. I'm running the latest version.
Any ideas what's going on or how to sort it?
