Hi, Thanks for the response. In retrospect the problem may be isolated to a particular project. But I'm thinking that failure cascaded to subsequent attempts to load other projects and it appeared to me to be related to all 'Sonar' projects. The project still get to the "Loading UI" and stops. But now other projects seem to be working fine.
Good thing too... I really liked the changes to the new Arranger feature and I was bummed about having to give that up!
