I will try to reinstall the pre-release tonight or over the weekend and post screen shots. Basically:
When I close Local, and am monitoring task manager, the local process groes from a foreground process to three background processes. They will stay there. Two do not consume any CPU cycles but one a small amount. They all have the green Local ICON.
When starting Local, I get the blue circle for a moment, but Local does not start.
If I go back to task manager, end the tasks (usually ending the one on the bottom releases all of them), then Local starts with no issues.
I will check to see if any docker-machine.exe processes are hanging about. But I have not had issues with those directly.
