dosemu 1.2.0: oddity when two instances open

I notice that with xdosemu 1.2.0, if I have two instances open on my KDE 3.1.5 desktop (running under Libranet 2.8.1), the following occurs:

If one instance is running an application loaded via a batch file, and that batch file ends with 'exitemu' as its last line, then whatever keystroke was fed to that application to exit that application, is then fed to the other instance of xdosemu.

For instance (this is the instance I first noticed this), say I have two instances of xdosemu running. In one, I have quicken running via this batch file:

        d:
        cd \quicken
        q
        exitemu

The keystroke that I use to exit Quicken is x. When I hit x, that xdosemu instance is closed and I see the letter x entered on the command line in the other instance of xdosemu.
