Problem with shotdown and statup of virtual device

Sometime you end up with a hanging device. I have discovered the problem, when i change resolution om my pc fx using the projector. At this point the virtual device  abort and can't start again.

Solution:

Device from AVD installed with the Android SDK:

Find the SDK - normaly it will be in "C:\Users\xxx\.android\avd" where xxx is your username.
Find the virtual device and delete all files starting with lock extention

I have made myself a commandfile with the content til make it easy
------------------
CD C:\Users\bjbu\.android\avd
RMDIR *.lock* /s
pause

Genimotion device:
Start VirtualBox manager and stop the virtual mashine from here
