Check Taskmanager to see if the app is in memory. A lot of applications check to see if they are already in memory. It sounds like the app doesn't exit cleanly in the first instance and then it thinks it is still loaded in memory at which point it calls the exit procedure, which isn't working correctly in the first instance.

Maybe :D

you ask about app bug or as i understand to run it in many instances(like use 4 cores for single threaded apps)

for this you can debug app and look where is checks if its already running.

start with openprocess,findwindow,openmutex.

Probably as human says - best bet is if it creates a mutex (perhaps with app name or something) then subsequent apps check if it already exists.

I'd go with CreateMutex/OpenMutex.
