how to reproduce:
- open a few winscp sessions via RDP (ssh or ftp, it does not play a role)
- close RDP without unlogging
- re-connect via RDP
- try to browse directories via opened sessions in WinSCP
the main reason why we use RDP on Windows 10 is the store of the opened sessions + text files + browser and else which makes it very comfortable to return to the same work state as RDP was closed.
in recent (in last cca 1 year) of upgrades of WinSCP this bacame a huge problem for us, it just takes a few minutes for WinSCP to get working after RDP reconnect.
we have about 7000 ftp/ssh accounts set up in our WinSCP, using AES encryption with master password. cleaning session cache in WinSCP solves the problem until another few tens of connections is made.
