Sometimes (I should say often) I want to drag a file from WinSCP to the desktop (Win7 64 & portable WinSCP) and sometimes it works, sometimes it does not. This is the first problem I want to report.
What does happen, when it does not work?
When it does not wotk, I must use the F5 (Copy) and what's annoying (and probably not intended) is that it does not remember the last path I selected. Yes the path I'm looking for is in the list, but it's not showing as the default one, even if it's the last one I've selected. So I must open the dropdown list and select. Can this also be fixed?
You are using Command interface. With Commander interface, destination always defaults to the path in an opposite file panel. Based on the way you use WinSCP, I would suggest you to use the Explorer interface (it remembers the last destination directory used):
