I'm not sure if this is a known issue with Safari, but on certain sites (e.g., circuitity.com, bestbuy.com) when you click on a dropdown menu and move the pointer to select an item from the menu, the menu disappears! As you keep moving the pointer down, the individual items show up, but the rest of the menu is not visible. Is there a fix for this in Safari, or should I get a different browser that handles the "optimized for IE" pages correctly?
