Summary	08609: mjsenka: Game randomly exits in an unstable manner
Description	This was first noted to crash one of my builds, usually on exit. Therefore it was checked against current mame git (pretty much what will be in 0.254) and while there was no actual crash, it misbehaves when run from the main menu. When run directly from command-line, no problem. When run from the menu, often when exiting you don't go back to the menu, you are back at the cmd prompt instead. Sometimes it won't even start, it just dumps you back at the prompt. The behaviour is completely random.
Steps To Reproduce	Start MAME, to get into the inbuilt UI. Choose mjsenka and run it. If it starts up, wait for attract mode, then press Esc. You should be back at the menu, but you may find yourself at the cmd prompt instead.
Additional Information	Game is marked as not working, but even so it should not misbehave like this.
