It is really annoying after hibernating or after a lengthy disconnect all the internal text editor windows become inaccessible due to the password prompt window. The main window also becomes inaccessible which is annoying.
And sometimes the dialog doesn't even show so you have to force close WinSCP. I can interact with the main window by doing things like ALT+F and etc but I can't click on anything or open up another password prompt window to log back in so I am forced to force close WinSCP.
Also option for integrating password request box into the main window would be nice too.
Also I'd like to add that multiple tabs is effectively becomes useless because once 1 session disconnects and requires password, the entire main window is locked so you can't use any of the sessions until dealing with that 1 session.
