How to run a full screen app in a Window?

[feuerschlange]

How do you run a full screen OS X app in a windowed mode?

I have one app, that I want to run parallel to my other open apps and lots of windows.

I am annoyed, every time I focus on this app, that my secondary screen goes blank and the small little app takes my whole primary screen.

If it's a full screen app, you generally can't run it in windowed mode if there isn't an option for it in the preferences.

A long shot.... but who knows:

Usually there is a .plist file associated with the app (usually in ~/Library/Preferences/), and sometimes if you open that file (like with Text Edit), you might find a line containing something like "windowed-mode full screen = TRUE".... edit that to FALSE, and see if it had helped.

Good luck.

Too bad - no luck here.
The app is an old game, called Solarian II.
It runs in full screen, completely darkening my secondary screen too and actually only takes 1/4 of the main screen, as it does not scale.
