title: MouseMove event repeating every second
body: <p><a href="http://jsfiddle.net/MrkY9/" rel="noreferrer">http://jsfiddle.net/MrkY9/</a></p>
  
  <p>My computer (and so far, no other computer among my coworkers) is exhibiting an issue in Chrome, IE, and Safari (but not in Firefox).  Simple <code>mousemove</code> code, such as the following (already running on the fiddle above) properly catches <code>mousemove</code> events, but then as long as the mouse is in the div, catches a <code>mousemove</code> event every second - even though I'm no longer moving the mouse.</p>
  
  <pre><code>var number = 0;
  $("#foo").on("mousemove", function() { this.innerHTML = number++ });
  </code></pre>
  
  <p>This seems to be a browser-based problem, since it doesn't exhibit on FireFox.  (Nor does it occur on Windows itself.  Even when the counter is going up, if I leave my keyboard and mouse alone, my screen saver eventually kicks in.)  Before concluding it's not a system issue, I tried replacing the mouse and switching the USB port it's plugged into.  Not surprisingly, none of those solutions resolve the issue.</p>
  
  <p>I haven't figured out how to test this in anything other than javascript in a browser.</p>
  
  <p><strong>Questions</strong>:
  Has anyone encountered this before?  Is there anything I need to do to catch it?  I have code far less trivial than this fiddle that rely on knowing when the mouse is and isn't moving.</p>
