I am unable to expand a particular folder which I have verified contains files. In this case a number of XML files are on a Linux box which I view via a Samba mapped drive. I can see the files via Windows Explorer as shown in the attachment. I have restarted the application but the problem persists. I am able to expand a similar folder which contains similar file types. There are 54 files in this folder in this instance. I can search in the folder, find files and open them without a problem.
