IE6.0 doesn't seem to like setting a select element's innerHTML to anything other than an empty string. It will allow adding options via document.CreateElement and .appendChild(...):

To clear and populate a <select> element:

// sel points to a <select> element
sel.innerHTML = '';
var option = document.createElement('option');
option.value = 123;
option.innerHTML = 'test';
sel.appendChild(option);
