Need WinSCP to work when I echo a message from my .chsrc

I've added a couple of echo statements to my .cshrc file in order to diagnose a seperate problem (scp from cygwin suddenly stopped working).

With the echo statements added WinSCP gives an error dialog when I connect. I've had this issue before with echo statements.

What do I have to do to get WinSCP to work with echo statements in the .cshrc?

Thanks.
