--- Comment #25 from Robert Wilhelm sloper42@yahoo.com --- Created attachment 72180 --> https://bugs.winehq.org/attachment.cgi?id=72180 test case
Small testcase. Copy it to c: and run wine iexplore file://c:\radio.html
document.FormName.RadioName[0].checked does not work, but document.FormName.RadioName.checked works on wine.
Maybe some issue with HTMLFormElement_get_dispid() in htmlform.c?
