Just upgraded to IE9 and using JavaScript API 2.3. I'm doing a simple point identify on a polygon with lots of vertices with the 'returnGeometry' option set to true. IE9 falls over with an 'Error: Out of Memory' exception.
It's definitely the 'returnGeometry' option that is causing this as it works when it's set to false, but it doesn't happen in IE8, IE7 or Firefox when 'returnGeometry' is set to true. Any ideas if there's a setting in IE9 or IIS that I need to tweak to take care of the memory issue?
