Yeah I'm looking at the network tab. I saw that Fiddler is free, and unfortunately that makes middle managers more likely to say no than if it was $1000. It took me weeks of fighting to get Google Earth installed
I'm starting to think it has to do with the test server environment. I just found out that the last time it was used was 2012! The crossdomain.xml had mysteriously disappeared off that server years ago, so I wonder what else went missing...
