Grid ROW-color rollover vs. selected

COuld anyone help me solve the following:

At this moment when I click on a row, this row is selected and gets an alternate background color.

What I would like on my website displaying the table is the roll-over function....: if I move my mouse over a row, and on mousedown...it gets the alternate backgroundcolor..........when I move the mouse out of this row, and on mouse-up, the original background color must be restored.

Probably this is hidden somewhere in the "grid.css" at a place I cannot find it.

anyone?

thanks !
