Are you sure that you are running the same version of WinSCP on both machines?

Thanks for the Information - it works fine now. Strange that it works under Win2000 but not XP with the same target.

Since 3.7.1 WinSCP tries to use --full-time parameter when listing directories to get precise timestamp. When it detects that the server does not support the parameter it stops using it. In your case the detection fails, because the error message comes too late (difficult to explain shortly). However you may manually disable the attempt to use --full-time.

I am using WINSCP to connect to a LEAF-Bering firewall (linux / Busybox system).
I have been using 3.7.0 (Build 254) very successfully for some time.
On upgrading to either 3.7.2 or 3.7.3 the program fails to show the root directory of the target host.
Pressing "reload" causes the following error:
-------------------------
Command 'ls -lad --full-time "/.."'
failed with return code 1 and error message
ls: unrecognized option `--full-time'
BusyBox v1.00 (2004.10.13-18:20+0000) multi-call binary

Usage: ls [-1AacCdeFilnpLRrSsTtuvwxXhk] [filenames...].
-------------------------
from busybox.
WINSCP is running on Windows XP Professional. I have tried running 3.7.2 on a (admittedly under VMWare) Windows2000 box to the same host and it works without error.
Here is an entry from the SCP log file:
