Now it works. I can move in and out of it, create files there, etc. If I remove the folder the link breaks but behaves as expected. If I make the folder a little shorter and create a file in it, I can create and remove the symlink to the file, as well. If you can suggest some other tests I should consider, I'd appreciate it. -- You are receiving this mail because: You are watching the assignee of the bug.
