With version 3.5 I ran into an issue of background color for the Go button;
The Search bar has a Go button on it so if you set the search bar background to a color the Go button needs to be build with that same color
BUT:
That same Go button is used everywhere, a good example is the registration page, the Go button on the search bar with the backgound to match now appears below in the Terms & Conditions with the same background.
So -> search.tpl -> search_head.tpl -> go_image.tpl
Since go_image.tpl is common to all calls for a Go Button make a new gob_image.tpl and have search_head.tpl use it. In the gob_image.tpl use the correct image that has the background.
The other problem is <A> class, there is none but that is another issue.
