This is true of any executable on almost any system. If there is no 
deliberate pause-before-terminating, then the program will terminate and 
the window will close. This has been asked so many times on these lists

Putting raw_input() at the end is not a workaround. It is the solution. 
Unless you want to redesign the operating system.
