Thanks Martin. I ran the debug version of WinSCP you had provided and emailed you the trace file.
Thanks for your report.
I have sent you an email with a debug version of WinSCP to the address you have used to register on this forum.
I'm not sure what I may have changed but, a listing of local files in the local panel is no longer being displayed. I can show the local directory tree which displays my directory structure on the local machine although the panel below it which would normally display the local files within the directory I've selected is no longer being displayed. The panel is displaying the total number of files and size within the directory I've selected although won't list the files.
BTW, I'm running WinSCP version 5.9.5 on a MS Windows 7 Pro system
