Vista - Mouse Hover-can not turn off

Holders of great knowledge, I have read different posts on deactivating the annoying behaviour of the a mouse hover functioning as a double-click. I have tried all recommendations, for example, turning off tapping, turning on double-click in folder options, turning off the select window box in Ease of Access. I have a Toshiba Satellite A205-7497 with Vista Ultimate. Still if I rest the mouse over a selectable item, in just a couple of seconds the item is selected-just as if I had clicked/double-clicked on the item. Mouse is a Logitech bluetooth model. Help me get rid of this annoyance. Thanks, Karl
