Why would you think it is a bug in the browser, and not in the javascript
code itself? Which is more likely?

It is a bug in the Javascript code. It is an accident if it works in
any browser (IE is known to be very accident prone).

More precisely, the error is in the line:
onChange="choos eKeyboard(docum ent.choose.stat e.options[state.selectedI ndex].value)"

Some browsers allow you to refer to named forms as properties of the
document area. It is still not as safe an assumption as writing
document.forms['choose']
Some browsers also allow toy to refer to form elements as properties
of the form. It is safer to use the "elementes" collection.

Very few browsers allow you to access named form elements as properties
of the global object. That is what the above line tries:
state.selectedI ndex
There is no global variable called "state". What should be writte is:

onchange="var select=document .forms['choose'].elements['state'];
chooseKeyboard( select.options[select.selected Index].value);"

Then it will work in other browsers than IE.
