I'm creating a plugin with setup pages in the dashboard, however, I can't seem to be able to disable my submit button.
The disabled="disabled" works in IE in the back-end but not firefox, chrome or safari.
<input type="submit" name="update" value="Update" disabled="disabled" />
I can get this to work in all the browsers in a test php file, but for some reason in the dashboard on my admin pages for my plugin its still accessible.
Thanks in advance,
