I just change my NSWindow from NSBackingStoreBuffered to a NonRetain one and my application do not crash anymore.
Unfortunatly, as expected, my window is clipping .... how ever i just realize that the crash might have a relation with the NSWindow double buffer mechanism. So my solution to the problem was instead of replacing the NSImage using setImage, i grab directly my NSImage from the View, then pick the representation and write directly into it. It is as a matter of fact, a way better effective way of doing what i was doing and it's avoiding all my release problems..... thx -- I.
