All, I have a Tk app that launches an external program via system. 
system $exec_string
   if ( $AUTO_LAUNCH and $file_name );

[download]
This successfully launches my program, but the Tk GUI hangs until I exit out of the app. I know this is the documented behaviour of the system function.
My desired behaviour for this application is to launch the external program, keep it open for future manipulation, but allow the perl script to return and be able to launch another instance of the external program.
I have attempted using exec, but this completely closes down my script. I have tried eval'ing the exec, and that doesn't work. I have tried wrappig the exec in another block, and I couldn't get that to work either. I read about IPC::Cmd, and I couldn't get that to work either.
Is it possible to do what I want? Can someone point me to references on how to accomplish this?
Thanks, David
