pb with resume

I currently use Winscp 4.02 with SFTP protocol
After a connucation break, the delay before trying to reconnect to the server can me modified in preferences/transfer/resume tab

This setting works fine in GUI mode but doesn't change anything if I call winscp from a Dos box.
I do create a saved session and call it from command line

where is the problem ?

- do we use default transfert settings or others settings when calling WinSCP from Dos ?
- are we automatically in background mode when calling winscp from Dos ?

Thanks for your help

The script should immediately reconnect, if "option batch" is set to "continue". Apparently, there's a bug. It will be fixed in the next release.
