PG, the code isn't supposed to have any calls to StartIO() or ShutdownIO(), those are methods that are invoked by the VB application after it creates an object out of my DLL.

I will look more in syncing the threads, I need a way to delay 'global destruction' of the process until the child has exited. I can't use 'join' since that halts the return from InitIO() until the child thread returns and the VB app is looking for a return after calling that method before it continues.
