When I open the sonos app on my desktop it says "The application “Sonos” unexpectedly quit while trying to restore its windows. Do you want to try to restore Click Reopen to open the application again". However, when I click 'yes' it then says-"Click Report to see more detailed information and send a report to Apple.its windows again?" and closes. I don't know what to do, if I call Apple they'll just say they can't deal with downloads that don't relate to Apple. If I ask Sonos, they'll refer me to Apple. iPad and iPhone apps work fine. Do I have a bug? Please advise if anyone has experienced this before.
