CPU used at 100% during reconnection attemps

My problem is that when the connection is lost between WinSCP and the server(for example the network cable unplugged) the CPU usage is at 100%.

And so it's a problem for the other application running...

The message returned by WinSCP in command line mode is "Network error:no route to host".

I thought I could change delays between two connexion attemps...to use less the CPU.
How could I change this ?

The delay I was searching for was in fact a problem with my own delay in my batch file...

So this problem is solved ! The first which does.
