As a co maintainer of a SDL program starting fill screen by default, the
mame arcade emulator, I would like to have your feed back on that one.

If you start mame and then exit it, does it breaks your multi head setup
? If yes then I would change the default startup mode to windowed mode.
I don't have a multi head set up to test.

Thanks
