submit button css in a portlet, specific button, mouse over effect, forms.css, developer tutorail

G L	:
		We have a custom theme in place that works well. My particular problem is a specific portlet with form buttons that are disabled at times. We have a portlet css file but I can't get the CSS to stop the button background from changing to a light blue color on a mouse over. It looks disabled until you hover over it with the mouse then the background changes giving the illusion of an active button. Below is my current CSS. It works with the exception of the mouse-over effect I'd like to disable for this specific button. Thanks.
Mazhar Anwar	:	You can override the following styles in your custom.css
		For reference, check out forms.css in theme_folder/css folder.
