VSS History question

I have a step based off of the "SourceSafe.bld" sample project to retrieve the History for a list of projects when I attempt to Test it the Build Status shows "Building...", but in the Output window the step seems to STALL at the point below and I end up having to Abort the step.

--------------------Starting Build: 'BuildProjects.bld'--------------------
Building project step 'History'...
Step default property 'Operation' = 'History'

I would appreciate any suggestions. I've been trying to resolve this for several hours w/o success.
