Hi,

Just reconnecting to a server using a SSH key :
CentOS Linux release 7.7.1908 (Core)

WinSCP error message popup "invalid memory access"

SFTP browsing OK, but Windows pannel freeze.

Just close WinSCP and reopen it, it's OK.

Thank you and have a good day.

Your work is incredible and soooo usefull !
