--- Comment #23 from Robert Wilhelm sloper42@yahoo.com --- Thank you for download link.
I looked at your log again, OnScriptError is called nine times.
First is document.writeln as reported in comment 21, all other are about something like
if (document.RTForm.selAuthRadio[0].checked)...
where document.RTForm.selAuthRadio[0] is no object.
I made small test html file with a radio button and it worked as expected using wine iexplore.
Maybe we can extract testcase from autocad installation.
