I use 4.3.6 (1655) on Win7.
What version of WinSCP are you using?
My WinSCP seems to be in Love with my secondary Monitor. I can move the Window to my primary Monitor and work there fine, but after closing an reopening just the Login Screen will be one the primary Monitor, but then the Connection Dialogue an whats most annoying the Main Window pop up on the Secondary. BTW the Position at Closing on Monitor 1 is reproduced on Monitor 2 at Opening. When Closing the Window on Monitor 2 all Windows (Login, Connection and MAin) will open on Monitor 2. Please Help. THX
