The OS X Finder offers a number of different views for organizing folder contents; however, in some of these views you may notice periodically that contents will shift around. This usually is not an issue, but sometimes it may result in the window view switching to a different position, resulting in you losing your place. This can be especially frustrating when you are managing a long list of items in a folder and the view keeps returning to a specific locaiton in the list.
This generally happens because you have the Finder view listed by date modified or a similar criteria that can be dynamically updated. In these cases, even if you have not adjusted the file, a background task or other program may do so, and this update could result in the file disappearing from view. If the file is selected, then your view may follow the file to its new location in the list.
To prevent this from happening, try reorganizing the list view by a different criteria. To do this, with the folder open in the Finder you can press Option-Command-0 (zero) or go to the View menu and choose "None" from the Arrange By submenu. In addition, if you are in list view then after setting the arrangement to None, be sure to sort the list view by a fairly static column category such as the item's name.
With these changes in place, the folder view should not shift around when items in the folder are updated.
