I've got a suggestion about modifying HTML.

So, IMHO <label> element should distribute mouseOver and mouseOut events 
to linked object (set by LABEL's "for" atribute to object's "id" value)).

Then it will be like in WinXP: when you mouseOver text labeled to (for 
example) checkbox, checkbox changes its color.

Now LABEL distribute only Click event 
(http://www.w3.org/TR/html401/interact/forms.html#edef-LABEL ), but i see 
no reasons why HTML shouldn't handle mouseOver event.

Best regards,
