User-Agent: Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7a) Gecko/20040219 As can be seen in the test case, if a radio or checkbox-type input element has the disabled attribute set, the element still displays as per the standard Windows UI element, giving the impression that it still accepts user input (to change state etc.) Reproducible: Always Steps to Reproduce: 1. Load test case 2. Observe! Expected Results: These elements should be greyed out (or whatever the Windows theme for disabled input UI elements should be) rather than the default. This gives the impression that these elements are interactive when in fact they're not (clicking them yields no result, in a similar manner to an element being manipulated via JavaScript). My experience was with Windows XP Professional using the 'Classic' (e.g. Windows 2000) appearance theme. I don't have the ability to change the theme so I can't test if it happens in the default ('tellytubby') theme.

This is a problem with the windows theming code, not with form controls... The default form control styles _do_ look different when disabled.

Dupping forward to bug with more information.... sorry about that. *** This bug has been marked as a duplicate of 237138 ***
