Help, no window events when using JavaClassToolAgent

I am using the shark client API to instance the shark engine and run an XPDL workflow.  Within my XPDL I run another Java application using the JavaClassToolAgent.  The problem is that when my Java application opens in a new window I can not control it.  The minimize, maximize, and close buttons do not respond and I cannot move the window around.  I don't have this problem when I use the RunTimeToolAgent to run notepad, or when I use the Shark Admin GUI to run my applicaiton.  Here is how I am running my process:

WfProcess proc1 = conn.createProcess(pkgId, ProcName);
proc1.start();

Am I missing something important here?  I left out the code to configure and connect to the Shark server because that all seems to be working and I don't _think_ its part of the problem.  What does the Shark engine do different to launch a process?  What I can I do to make my process handel the window events (close, minimize, move, etc)?
