I will investigate what could cause this issue. I am unsure of any alternative solutions at present or what could cause this. I know other applications written in any other language can have similar issues, and it may be isolated to certain Windows related setups. Can you go into your Event Log and see if there are any issues there that Windows may have reported?
Also see if reinstalling Story Creator helps. It may be that a configuration file got corrupted the last time the app exited.
