Thanks. I finally got the timebroker service disabled and my metro apps mostly run OK. However, I had previously used the script to delete all my apps and have only restored the news, finance, and weather as test cases. So, I can't find an offending app to delete (although I had one of those "time" apps downloaded early on which likely created this mess originally). Thus, when I re-enable the timebroker service, my metro app hangs return. Does anyone know what happens if I just leave it permanently disabled?
When I said my apps behaved mostly, my news app hangs with a javascript error reported. By trial and error, I found that I can make this go away by disabling the live tile feature. Once I do so, I also find that I can re-enable it without the error recurring.... at least until I restart the PC again. Any ideas how to fix this?
