<p>If you <em>can't</em> perform a review task, it will be grayed out, as at your rep level should be the case with all except the <code>First Posts</code> and <code>Late Answers</code> tasks. When I'm around, I'm one of those zealous users that's causing your problem ;) I check the review queue between practically every page navigation precisely because these tasks' queues empty so quickly – of course, in the process, I exacerbate the "problem" in which I share. My solution was to hit the next tier of privileges so I could start reviewing suggested edits too. I imagine higher-rep users will be alternately relieved and disappointed that my overzealous editing won't need reviewing anymore, nor fertilize their badge farms :) In summary, I'm afraid the only solution is to keep up with the crowd! Good luck to you (it's not easy in this crowd!), and may the fastest reviewer – <em>who doesn't sacrifice thoroughness and tact</em> – "win"!</p>
