title: Can't set breakpoints in Eclipse
body: <p>Following the Android notepad tutorials using Eclipse 3.4.2 on OSX 10.5.6.</p>
  
  <p>I'm instructed to set a breakpoint in one of the following ways:</p>
  
  <ol>
  <li><p>Double click on the gray bar to the left of the editor pane.</p>
  
  <ul>
  <li>this just brings up the "Add Bookmark" window</li>
  </ul></li>
  <li><p>Select "Toggle breakpoint" in the context menu</p>
  
  <ul>
  <li>the only options in the context menu are "Go to Annotation..." (which is disabled), "Add Bookmark", "Add Task", "Quick Diff", "Show line numbers", "Folding" and "Preferences" </li>
  </ul></li>
  </ol>
  
  <p>My guess would be that the editor's in some mode that doesn't allow breakpoints to be set, but I'm only an Eclipse newb. Anyone able to lend any advice here?</p>
