I've already checked to make sure I'm not running in IE7 compatibility mode, which I'm not.
When reviewing questions, regardless of the choice I select ("Not Sure", "Approve", "Recommend for Deletion", etc.), the "Loading next item..." message will appear, but the page will hang and not progress to the next item.
In the bottom left corner of the browser, I noticed a warning, so I clicked it and found the following:
Webpage error details
User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 5.1; Trident/4.0; .NET CLR 1.1.4322; .NET CLR 2.0.50727; .NET CLR 3.0.4506.2152; .NET CLR 3.5.30729; .NET4.0C; .NET4.0E) Timestamp: Wed, 17 Oct 2012 12:52:57 UTC
Message: Object doesn't support this property or method
If I refresh the browser, the next question/answer for rewview comes up successfully, but when I act on the next question, the "Loading next item" message will hang again.
