Problems sproc-ing a pf process...

I'm having difficulties attempting to repeatedly launch Performer on a sproc.
My basic goal is this:

  o have the parent application have the ability to launch/destroy
    a performer process at will. Only one pf process will be active
    at any given time.

The problem I'm running into is that although the first sproc works great,
subsequent sprocs do not, complaining that:

PF Warning/Usage(2): pfInit() Already initialized. Must call pfExit()
before reinitialization.
PF Warning/Usage: pfMultiprocess() Must call before pfConfig.
PF Warning/Usage: pfConfig() Cannot config more than once.

and later, when attempting to launch a window:

X Error of failed request: BadAccess

I have attached a small (1k) chunk of sample code which illustrates this
problem.

If anyone has any clues/ideas, I would be very appreciative of any help...
Thanks!

Bob
