MC needs a better way to bring this window back. This "alt & enter" method is lame.

If you follow what drowbe says:
Okay...I just tried it. I opened it as a window and then hit the red "X" to close it. It returned to MC; however it was "hidden". It became merely a titlebar that says "Action Window" with a few buttons. The far right button (round and blue, in the PixOS skin), should bring back the action window for you. IT will become a window again. You can then right-click over it and uncheck "show as window".
It should work - It works for me anyhow.
However even more, if you right click on the "Title bar" when it is closed - you can toggle the "show as window" state anyway.
So if you have the action window and right-click the title bar of it and "show as window" you will get a seperate window. If you close this, you will now get just the "title bar" part of the action window showing. You can right-click this and turn off the "show as window" setting and the Action window should appear where it normally is.
Hope this helps!
