God I'm having awful issue with EZCA and the 777 at the moment. I've  ran the tool each time I install a new aircraft. And I currently have a similar issues with changing views as well.And I cant figure out the relationship with the 777 and EZCA but it's plain to see that they don't work well in conjunction with each other. No other add-on aircraft except the beautiful 777 gives me as much trouble with EZCA :-[. Running current updated EZCA 1.7 and win 8.1
