Terminate action option not working

[teognost]

In the VBP project I have a step (RunProgram) which is launching some internal tool (an exe file).Time out for this step is set to 5 hrs (Terminate action if not completed after %UNIT_TESTS_TIMEOUT% seconds )
using macro UNIT_TESTS_TIMEOUT.However -the build process remains frozen as it does not go further than this step.I would expect after 5 hrs the step will be forced to close and move to next one (on other box it happened that way in the past).
I am using VBP 6.7a,box is a Virtual machine with OS =Microsoft Windows Server 2003 R2 Standard Edition.
