I'm writing a script that proactively validates data input.
Under IE, throwing up an alert seems to interfere with the behavior of
radio buttons. In other words, if changing the value of the radio button
field fires the validation, the radio button either isn't set or isn't
displayed correctly after the popup is dismissed.
If I stick the error messages in a non-editable textarea field, the
textarea field doesn't get refreshed.
I tried "focus" - didn't help.
Mozilla works perfectly of course.
