That's the part I thought was odd, too. So building with VisBuildPro.exe doesn't exhibit the problem, but using VisBuildCmd.exe does? Very strange, since the very same underlying build component and SourceSafe action are used in both cases. Ultimately, either way, it invokes CreateProcess on a command-line call to ss.exe. Could you post or send to
support@kinook.com:
1) The info from Help | About | Install Info in VBP
2) The info from Help | About in VSS Explorer
3) The .bld file with the SourceSafe step that's failing to build, along with a build log of the step output when it fails
