Seeing this made me a happy woman this morning... Todd Bleeker has a nifty trick that allows you to set list or library items to open up in a new window. It has a few restrictions... it needs to be added to each instance or view of the list or library, it will apply to all of the list or library items, and it doesn't seem to work for the Links web part in Summary view (view with the links as bullets).
But it is a handy workaround for when SharePoint users ask for the functionality to open items in a new browser window.
