Rails spinoffs - Mar 2008 - Form.Element.disable() shifts docus

I''ve found in Firefox 2.x, using Form.Element.disable() shifts the
focus from the current form element somewhere else in the document
(possibly to the disabled form element right before it''s disabled).

The effect is that the BLUR event is fired on the current form element
when Form.Element.disable() is invoked and it doesn''t seem that focus
should have ever left the current form element.

In IE7, this does not happen.  Any ideas?  For example...

<form action="" method="post" name="myForm"
id="myForm">

<input type="button" name="myButton"
id="myButton" value="Click Me" /
><br />
<input type="text" name="myTextBox"
id="myTextBox" value=""
onblur="alert(''Focus left!'');"
onkeyup="$(''myButton'').disable();" />

</form>

Help!  What can I do to prevent the current form element from losing
focus?

Disabled form elements by there very definition cannot have focus. The
blur() event is fired just before the control is disabled.

IE is doing it wrong :)
