204	error after showing volume outline box	Elaine Meng	Tom Goddard	"The first time I tried to show a box I got a long traceback that went off the screen, so I couldn't capture its contents.  Then I restarted ChimeraX and just used the following commands.  I did see an outline box but as soon as I tried to manipulate the view there was a traceback (also below) and redrawing halted.

open 1zik
molmap /a 8
volume #2 showoutline true

Error in drawing scene. Redraw is now stopped.
