avoid a continuous stream of error messages. To restart graphics use the

Hi Ben,

Thanks for reporting this problem. It was fixed on October 24th of last year, and your ChimeraX is from June 6th of that year. If you upgrade to the last release or release candidate, you should be able to restore your session.
