(Sorry for posting the report as a guest).
I am using the latest available version of WinSCP (3.6.1, Build 221). Here is a problem that looks like a bug to me:
1. Connect to a remote server. You are in your home directory.
1. Click the "Open directory/bookmark" button on a right-side panel.
2. Type in or paste any valid path (that differs from your home) into the "Remote directory" field.
3. Click the "Add..." button.
4. Click "OK". You are in that directory now (the target directory).
5. Click the "Home directory" button. You are in your home directory.
6. Click the "Open directory/bookmark" button on a right-side panel.
7. Double-click the entry you have just added. You are not in the target directory as you would expect. You are still in your home directory.
8. Try to switch to that directory manually by double-clicking the folder icons (representing the directories).
9. When you are one level up from the target directory, double-clicking the target icon does not open the target directory. Surprisingly, it opens your home directory.
I found the workaround for the above problem: When you are one level up from the target directory, click the "Refresh" button.
This is the second time I am sending you an error report. First time I sent another report under another user ID (probably Vladimir Anisimov), but it was so long ago that I forgot my password. You were able to reproduce the first error I reported and fixed it soon after (thank you!).
