Back in July I blogged about the SQL Server 2012 Extended Events Add-in to Manage 2008/R2 Instances. Unfortunately, despite having multiple beta testers using the add-in before the release, I started getting reports of the add-in crashing Management Studio. A new version of the add-in is available for download (https://www.sqlskills.com/free-tools/sql-server-2012-extended-events-add-in/) that addresses this and one or two other issues that were reported over the last month. If you have the add-in installed, it should prompt you to update the next time it loads. To install the newer version, you will have to uninstall the add-in and then install the new build.
