Now I'm thinking that maybe the condition of the options.sdo / config.xml files are not necessarily related to the hang. Sometimes it works for me, and sometimes it doesn't. But almost always after letting the car sit for 3-4 hours it will fail.
I set the Streetdeck Tray App to kill SD after 30 seconds of being hung (the minimum), and that usually kills it after about a minute.
Centrafuse 2.0 can't come soon enough.
