title: How do I delete an Eclipse perspective for a plugin I uninstalled?
body: <p>I was evaluating the Enterprise IDE plugin for Eclipse, and ultimately decided not to purchase it.  After I uninstalled the plugin, I was left with a bunch of perspective buttons (the ones in the far upper-right-hand corner) which I can't remove.  How do I get rid of the manually, without nuking my workspace?</p>
  
  <p><strong>Edit</strong>: To be clear, right-clicking and going to "close" does nothing.  Not even an error message.</p>
