Can't get rid of on hover effect for last item hovered over

[rymac]

I am trying to get rid of the hover effect. I have created my own CSS hover and selected effect, the gold color seen in the attached screenshot.

However, the last item in the grid or menu that I hover over still shows the light blue color effect, even when another menu item is selected, like in the attached screenshot.

How do I get rid of this "last hovered over" effect? Here's my CSS:

.cadenceCommon .x-grid-row:hover,
.cadenceCommon .x-menu-item:hover,
.cadenceCommon .x-grid-item-selected,
.cadenceCommon .x-menu-item:hover,
.cadenceCommon .x-accordion-hd:hover {
    background-color: #FFB500 !important;
}
