Subject: Question about using InterProcess Communication

I've been exploring the usage of IPC (InterProcess Communication) Library  
by Thomas Parslow and I have a question.

What I want to do is have a main application start a secondary application
and when the main application closes, close the secondard one. I've got  
this working.

The clinker is I also allow multiple instances of the secondary app.
However, when I use an ipc_CallProc or ipc_CallFunc routine to close the
secondary apps, only the first one gets closed.

Anyone have a solution?
