Measuring in Edrawings Publisher

I have a co-worker who regularly uses Edrawings Publisher(free version) to open SolidWorks part files and take measurementsfrom them. This has worked very well until recently. He downloadedthe Edrawings Publisher 2008 version after we switched to 2008.Here's the mystery - he can still measure pre-2008 SWorks partsjust fine but cannot do so on the 2008-created parts. The measuretool remains grayed-out and unavailable. Any ideas?SolidworksEdrawings
