Go find an xml file on a remote computer via WinSCP, go to edit that file just to view it. When done, close the edit window by the (X) on the top right and the hour glass takes considerable time before the window finally closes.

Are you able to reproduce the problem?

I have been connected remotely to the Linux Machine by SFTP. I had 4 files(.log extension) opened for a longer while. I have decided to close them all one by one, first one was closed correctly, on second one i noticed the error. Later i have closed rest of them and it went fine. I have been doing same action for a lot of time and it's first time i can see any kind of error in your program, it's very good. Thank you for working on it.
