this surprises me. I'll try that myself. Clearly it can work -- Jmol is
doing it already. What could it be? Miguel should know.

I don't think so. The code is simply this:
Eval e = new Eval(this);
if (e.loadScriptString(strScript, false)) {
e.runEval();
}
You could make a "budget" scriptWait that doesn't return any strings and
see if that works better for you:
void scriptWaitVoid(String strScript) {
Eval e = new Eval(this);
if (e.loadScriptString(strScript, false)) {
e.runEval();
}
}
Do you want to try that?
I do note that the Jmol.java piece of this is synchronized to prevent
multiple simultaneous scripting.
synchronized public String scriptWait(String script) {
return viewer.scriptWait(script);
}
could there be a problem with that?
