Using the latest beta of WinSCP4. When I start the "Keep remote directory up to date" and then push the Minimize button (next to the Stop button) nothing happens. Well, actualy the dialog becomes no longer modal, i.e. I can switch to the main window without closing the dialog, but it doesn't minimize. This doesn't depend on the option "Minimize to status area".
After I push Stop, and again call "Keep remote directory..." the minimize button starts working..
