I'm having a problem, I think. 😒

Whenever I run DOSBox and playing a game that can only be run with a BAT file, the exit command I've put into the shortcut won't comply. I have the command in the autoexec section of the .conf file.

Here's an example:

1@echo off
2mount c ".."
3c:
4cls
5KEEN7.bat
6exit

When I exit the game, DOSBox is still running and I see that little box with out-dated adverts for Commander Keen. Usually, DOSBox should terminate on itself here. But it doesn't.
I'm using the latest version of Daum (27 jan 2014). Could that be the culprit?
