Web designers should standardize on visual clues that indicate when the link will: 1) Just open something normally. 2) Open it in new Window/tab. Maybe browsers should automatically do something about those links? Like displaying a different cursor on mouseover? 3) Perform an action that doesn't navigate away from the current page. 4) Is not a real link and sits there only for mouseover events. This is often denoted by dotted underline, but no everyone uses that convention.
