Windows version does not respect close requests
Standard Windows requests to close the program should be handled apropriately
Any well-behaved Windows program must follow the platform's conventions. ADOM, unfortunately, has a few problems here. Most noticeably, when the user hits ALT-F4 or selects other methods of closing the program, (X button in title bar, Close menu command,) nothing happens. ADOM should treat these actions as a close request and respond appropriately.
Note that this does not necessarily mean immediately terminating the program. But completely ignoring the request is never the right thing for a program to do.
