Daniele has posted an update to the MPViewer app to fix a couple bugs. One is related to the IIS Management Pack and how it generates alerts and the other fixes an unavailable menu item.
If you remember, Daniele took over development from Boris Yanushpolsky in February 2012 and has since released close to seven updates to MPViewer. You can get the updated version, along with OverrideExplorer and Proxy Settings, from the following page:
