.NET DropDownList SelectedIndexChange Event Not Firing in IE 10

Question

In IE 10, when a drop down list selected item is changed, nothing happens. It doesn't post back. All other controls work except for drop down lists.

It appears to work when I switch to IE 10 compatibility mode.

Do you have the ASP.net Hotfix for IE10 installed?
