title: jquery ui autocomplete not working in ie8 (until page refresh)
body: <p>I am using jquery ui autocomplete it is working absolutely fine in all browsers except ie8.</p>
  
  <p>I have been doing some testing and there seems to be a strange bug. When I click on a link leading to the relevant page there is the following error generated by ie8 when I start typing in the autocomplete box:</p>
  
  <p>'object doesn't support this property or method'
  this error points to my development jquery(1.4.2) file at line 4955, char 5 which is the following line:
  return new window.XMLHttpRequest();</p>
  
  <p>However, if I simply reload the page the autocomplete works.</p>
  
  <p>I have added a random bit of data to be called with the autocomplete as I read that ie8 caches it ajax get requests but this does not seem to have solved the problem.</p>
  
  <p>Could there be a problem with the timing of the loading of all the relevant files including jquery? If so, how would I fix this?
  Any other clever ideas?!</p>
