Prevent clicking on view tab when editing a node I was wondering anyone knew of a module that would warn people when clicking on the view tab if they have made changes to a node, but didn't save it. For example, I've seen a few times where people would click on the edit tab to edit the node, then when finished, click on the view tab at the top next to it. This doesn't save the page, and they loose everything they just worked on. 

Any thoughts on how to warn people to click "save" first before navigating away?
See the content lock module:


  Features
  
  
  Concurrent editing:The user gets notified when he tries to
  edit a node, which is edited by someone else. He cant enter the edit
  mode.
  By node type: Configure content_lock to lock only specific
  nodes.
  By format: Configure content_lock to lock only specific input
  formats.
  No losing content by accident: User gets notified, if he
  wants to leave a edit form by abnormal conditions (close
  browser/window/link click). If the user confirms to leave, the edit
  lock gets automatically removed by an ajax call. You can disable this
  behavior in the admin menu.
  No forgotten locks: The user gets notified
  when he forgets to unlock a node. He/she will be asked to click on a
  link to unlock this node.
  Views integration: Show all open locks using
  any filters, as you have a views integration.
