An error occurred in drawing the scene. Redrawing graphics is now stopped to
avoid a continuous stream of error messages. To restart graphics use the
command "graphics restart" after changing the settings that caused the error.

ChimeraX does not support Windows 7 as it says on the download page. You should use our older Chimera program on Windows 7.

The error you are getting means your graphics driver is inadequate.

Please don't submit the bug report 5 times, one time is enough, it creates extra work for us.

[kbattula2@…]

Dear sir/madam,
                                Thank you for the reply. Excuse me for
submitting the error message more than once.
