    hi all

    please try:
    1 create new application using multi-document template
    2 do nothing, just run this new application using leak-checking instrument
    3 select save-as option - save panel appears ; expand it to show file icons
    4 do nothing, just wait

    result : you'll see memory leak

    also you'll see memory leak in apple's native example ImageApp

    the question: should I ignore such leaks in multi-document application or I did something wrong?

    Less lost in L.A.
    If no one replies back saying you did something wrong, then please file this with Apple as a bug.

    Every time I launch my application, and sometimes randomly while navigating through my UITabBar I get leaks from CoreGraphics for open_handle_to_dylib_path. Since I'm not doing anything directly with CoreGraphics, and I'm not leaking any UIobjects (that would use coregraphics) I assume its apple's mistake.

    I move on and hope Apple will fix it in the future. But in this case I'm only loosing 128Bytes at a time and it doesn't happen very often.

    the caller of the leak I wrote about is :
    -[NSNavFBENode _calculatePreviewThumbnailImageWithMaxSize:isThumbnail:]

    imho it seems like CoreGraphics problem ...
