Steps to reproduce:
* start FAR
* alt+f2, select WinSCP
* connect (I use ssh keys and Pageant)
* tab (to switch to left pane)
* f4 to edit a file
* f10 to exit
It doesn't happen always but most of the times. Five tries is usually enough to invoke it.
I think that it happens more often when I make a change in the editor and save it before exiting.
By "freezing" I mean that FAR Manager stops responding and I see what I saw directly before hitting F10. CPU usage rockets up to full.
FAR Manager 1.70 beta 5 build 1634
For testing purposes I moved all my FAR plugins (except for WinSCP) out of Plugins directory to be sure that it's not a collision with another plugin.
I've tried upgrading to FAR 1.70 beta 6 some time ago but I experienced some issues so I downgraded again.
If you are going to issue a fix you may read my other post about default SSH Compression. :-)
Thanks for your hard work
