[CONNECT] Selectively disable ProjectWise Explorer client

When ProjectWise (PW) Explorer client is installed it puts configuration file pw.cfg in MicroStation's config/appl folder.  That configuration file instructs MicroStation to pop the PW login dialog when it starts.

But how do I prevent MicroStation from showing that PW dialog?  I have only one project (workset) where I want to use PW.  Most of my work does not require PW.
