How to disable auto-maximize on re-open?

[Bazon Bloch <bazonbloch arcor de>]

Hello,

when a window is closed and its size is big enough, it will be opened 
next time maximized.
I don't like that. If I wanted to have a maximized window, I would have 
maximized it in the first place.
How can I disable this behaviour?

Thanks
