If at all possible, don't mess with the .js files. You need to figure out a
way to do what you want to do by adding JavaScript to your page, not
removing it from core files. That will only be a headache.
Here is the way to remove the progress monitor using the current code (to
be inserted in the page's <head> block):
var lc = LoadClazz;
LoadClazz = function() {
lc();
ClassLoaderProgressMonitor.showStatus = function() {}
}
======
LoadClazz is a function that JSmol to load the code that is in j2sjmol.js.
It's in that function that the monitor is set up, so overriding anything in
that files requires inserting code to run after LoadClazz() is run. Here we
just save that original function and instead have JSmol
a) run LoadClazz() as lc()
b) disable the showStatus function, so nothing is displayed
