[ccnet-user] pdfcreator hangs while running ccnet as a service

[pshek]

My build script is written using perl which calls pdfcreator to
convert doc to pdf. When I run the ccnet via console pdfcreator works
fine opening/closing MS word briefly while converting doc to pdf, but
when ccnet is run as a service pdfcreator hangs forever. I have
enabled interative service, but no luck. Please suggest any solution
to this problem.
