Mac OS X's placement of windows is determined by the .DS_Store files that are located within each folder in the system. When users change window size and location, placement information is stored in the .DS_Store file that is in the current folder being resized. This can be confusing to some users, because, in most view modes, the same window is used to show the contents of the opened folders. As such, if a user changes the size of a window with the "Desktop" being viewed, new windows may be in different locations because they are referencing a different .DS_Store file. Despite this default behavior, users may encounter bizarre window sizing behavior.
