The first time I change directory after pressing the Synchronize browsing button I always get the warning (Information)
Cannot open corresponding directory in the opposite panel. Directory browsing synchronisation failed. It has been turned off.
But the corresponding directory in the opposite panel exists and can be opened.
The solution is to press OK, return to the directory I started in, press the Synchronize browsing again, change again directory and from now on everything works as expected.
I am using WinSCP 3.6.8 (Build 245) on Windows 98 with SFTP (v3) and aes encryption.
Thanks for reading,
