title: HTTP synchronous request stops my GIF moving in Chrome and IE?
body: <p>In Firefox, I have a synchronous request that happens (it must be sync or the later JS will not run correctly) now in the XMLHttpReq function it basically changes one of the DIV's contents to a tiny loading logo (turning cog) so you can see progress... In FF this works 100% async or sync... Chrome and IE no such luck..?</p>
  
  <p>Can anyone help me or explain why please? Im guessing it something to do with them disabling ALL other processes but if this is so how can i get this to work OR evaluate and JS file after this original XMLHttpReq has loaded? </p>
