Visual SourceSafe Differences fails

[bradpitcher]

Hi,
I'm having trouble running a diff command with SourceSafe. It displays the differences just fine and accurate but the step fails with this error:
Process completed with exit code 1

It's ok because I got the output I needed and I can just tell visual build to continue when the step fails, but I just want to understand why and see if it's fixable.

Can anyone help me?

Thanks,
Brad
