Hi, Using asynchronous: false *really* locks up the UI in IE (and some other browsers). In this case, even though you've told it to show the image, it's probably not had time to actually do that (browsers usually queue these things) before the UI locks because of the synchronous call.
The best answer is probably not to use a synchronous call, but rather to use an iframe shim or something to make everything on the page unclickable while the call is in progress. Synchronous calls lock *everything* UI-related in that IE process, not just your page, whereas an iframe shim just makes your page unclickable (and provides an opportunity for you to show things a bit dimmed-out or something). It's also really easy. If you can't do that, you may have to change your approach to showing the image, because what you want to do is give the browser a chance to process any UI updates before you lock it, which is easily done with a setTimeout call (directly, or via one of Prototype's useful wrappers like Function#defer and Function#delay; Function#defer is just Function#delay with a 0.1 delay time). But you can't do that from within the onCreate callback. Instead, you'd have to create a function that you use to launch Ajax requests which shows the image, then schedules the Ajax call to happen after a brief setTimeout/ Function#defer/Function#delay. Even then, be wary that your new function triggering the request will return *before* the request is triggered, because of the setTimeout/defer/delay. HTH, -- T.J.
