The command works. But since it doesn't provide for which object the
coordinates are, I guess I will have to use 'jmolGetPropertyAsJSON' to
get all necessary information. I have to take a deeper look into that
before I am able to use it, but I like the possibility to get all
necessary information for all draw objects at once.

The freezing problem seems to depend additionally on other things. Today
Firefox didn't freeze either with or without the timeout. I restarted
the browser several times and never got a freeze. Yesterday I always got
a freeze, but I am not aware of any change (not even a reboot or a new X
server session). So 'jmolScriptWait' unfortunately still remains on my
"don't use it" list.
I noticed a strange behaviour of the 'show draw' command. If the
definition command and the show command are provided within a single
'jmolScript' command, no coordinates are shown. Only if they are
provided within different 'jmolScript' commands the coordinates are shown:
jmolScript("draw line1 (atomno=1) (atomno=2); draw line1; show draw;");
-> WITHOUT COORDINATES
jmolScript("draw line1 (atomno=1) (atomno=2);");
jmolScript("draw line1; show draw;");
-> WITH COORDINATES
Sometimes the 'show draw' command freezes Jmol with the following error
message (I couldn't figure out any specific condition, version 10.9.86):
java.lang.NullPointerException

Besides the Java console shows sometimes the following error message (no
