1368	Camera 360tb crash	tlskillman@…	Tom Goddard	"{{{
ChimeraX Folks,

On my VR laptop running Windows 10 and a week old ChimeraX build, I got the
following error. ""Camera 360"" works but ""Camera 360tb"" throws the error
below.

Thanks for any pointers.

Tom

PS - I was following the general sequence TomG showed in the nice video at
https://youtu.be/yOMKwCbXl0g .
