Here is one that's been driving us a little insane. We implemented the example script for JSONP from the jQuery UI page <http://jqueryui.com/autocomplete/#remote-jsonp> then right in place next to it, we wrote a minimally modified version.

Here's the kicker. The script from jQuery ui works in IE and ours only works in Firefox, Chrome, etc

The ONLY difference is our datasource. 

It there some magic thing we need to do to our data when we send it to the client? We've tried wrapping it in named functions, etc.

For giggles, here is the output from the working json service
